GHSA-3C4M-3XHW-2CR2
Vulnerability from github – Published: 2024-05-17 15:31 – Updated: 2025-01-10 18:31In the Linux kernel, the following vulnerability has been resolved:
drm/amd/pm: fix a double-free in si_dpm_init
When the allocation of adev->pm.dpm.dyn_state.vddc_dependency_on_dispclk.entries fails, amdgpu_free_extended_power_table is called to free some fields of adev. However, when the control flow returns to si_dpm_sw_init, it goes to label dpm_failed and calls si_dpm_fini, which calls amdgpu_free_extended_power_table again and free those fields again. Thus a double-free is triggered.

OESA-2024-1677 (CVE-2021-47269)
Vulnerability from osv_openeuler – Published: 2024-05-31 11:07 – Updated: 2026-08-06 11:07 – Source websiteThe Linux Kernel, the operating system core itself.
Security Fix(es):
In the Linux kernel, the following vulnerability has been resolved:
usb: dwc3: ep0: fix NULL pointer exception
There is no validation of the index from dwc3_wIndex_to_dep() and we might be referring a non-existing ep and trigger a NULL pointer exception. In certain configurations we might use fewer eps and the index might wrongly indicate a larger ep index than existing.
By adding this validation from the patch we can actually report a wrong index back to the caller.
In our usecase we are using a composite device on an older kernel, but upstream might use this fix also. Unfortunately, I cannot describe the hardware for others to reproduce the issue as it is a proprietary implementation.

In the Linux kernel, the following vulnerability has been resolved:
isdn: mISDN: netjet: Fix crash in nj_probe:
'nj_setup' in netjet.c might fail with -EIO and in this case 'card->irq' is initialized and is bigger than zero. A subsequent call to 'nj_release' will free the irq that has not been requested.
Fix this bug by deleting the previous assignment to 'card->irq' and just keep the assignment before 'request_irq'.
The KASAN's log reveals it:

Use-after-free write at 0xffff88823bc16040 (in kfence-#10): kmem_cache_destroy+0x1f/0x120 mm/slab_common.c:486 f2fs_recover_fsync_data+0x75b0/0x8380 fs/f2fs/recovery.c:869 f2fs_fill_super+0x9393/0xa420 fs/f2fs/super.c:3945 mount_bdev+0x26c/0x3a0 fs/super.c:1367 legacy_get_tree+0xea/0x180 fs/fs_context.c:592 vfs_get_tree+0x86/0x270 fs/super.c:1497 do_new_mount fs/namespace.c:2905 [inline] path_mount+0x196f/0x2be0 fs/namespace.c:3235 do_mount fs/namespace.c:3248 [inline] __do_sys_mount fs/namespace.c:3456 [inline] __se_sys_mount+0x2f9/0x3b0 fs/namespace.c:3433 do_syscall_64+0x3f/0xb0 arch/x86/entry/common.c:47 entry_SYSCALL_64_after_hwframe+0x44/0xae
The root cause is multi f2fs filesystem instances can race on accessing global fsync_entry_slab pointer, result in use-after-free issue of slab cache, fixes to init/destroy this slab cache only once during module init/destroy procedure to avoid this issue.(CVE-2021-47335)
In the Linux kernel, the following vulnerability has been resolved:
hwmon: (mlxreg-fan) Return non-zero value when fan current state is enforced from sysfs
Fan speed minimum can be enforced from sysfs. For example, setting current fan speed to 20 is used to enforce fan speed to be at 100% speed, 19 - to be not below 90% speed, etcetera. This feature provides ability to limit fan speed according to some system wise considerations, like absence of some replaceable units or high system ambient temperature.
Request for changing fan minimum speed is configuration request and can be set only through 'sysfs' write procedure. In this situation value of argument 'state' is above nominal fan speed maximum.
Return non-zero code in this case to avoid thermal_cooling_device_stats_update() call, because in this case statistics update violates thermal statistics table range. The issues is observed in case kernel is configured with option CONFIG_THERMAL_STATISTICS.

If a cell has 'nbits' equal to a multiple of BITS_PER_BYTE the logic
*p &= GENMASK((cell->nbits%BITS_PER_BYTE) - 1, 0);
will become undefined behavior because nbits modulo BITS_PER_BYTE is 0, and we subtract one from that making a large number that is then shifted more than the number of bits that fit into an unsigned long.

ALSA: emu10k1: Fix out of bounds access in snd_emu10k1_pcm_channel_alloc()
The voice allocator sometimes begins allocating from near the end of the array and then wraps around, however snd_emu10k1_pcm_channel_alloc() accesses the newly allocated voices as if it never wrapped around.
This results in out of bounds access if the first voice has a high enough index so that first_voice + requested_voice_count > NUM_G (64). The more voices are requested, the more likely it is for this to occur.

In this case, the netlbl_calipso_add_pass() function allocates memory for the doi_def variable but doesn't free it with the calipso_doi_free().

crypto: pcrypt - Fix hungtask for PADATA_RESET
We found a hungtask bug in test_aead_vec_cfg as follows:
INFO: task cryptomgr_test:391009 blocked for more than 120 seconds. "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. Call trace: __switch_to+0x98/0xe0 __schedule+0x6c4/0xf40 schedule+0xd8/0x1b4 schedule_timeout+0x474/0x560 wait_for_common+0x368/0x4e0 wait_for_completion+0x20/0x30 wait_for_completion+0x20/0x30 test_aead_vec_cfg+0xab4/0xd50 test_aead+0x144/0x1f0 alg_test_aead+0xd8/0x1e0 alg_test+0x634/0x890 cryptomgr_test+0x40/0x70 kthread+0x1e0/0x220 ret_from_fork+0x10/0x18 Kernel panic - not syncing: hung_task: blocked tasks
For padata_do_parallel, when the return err is 0 or -EBUSY, it will call wait_for_completion(&wait->completion) in test_aead_vec_cfg. In normal case, aead_request_complete() will be called in pcrypt_aead_serial and the return err is 0 for padata_do_parallel. But, when pinst->flags is PADATA_RESET, the return err is -EBUSY for padata_do_parallel, and it won't call aead_request_complete(). Therefore, test_aead_vec_cfg will hung at wait_for_completion(&wait->completion), which will cause hungtask.
The problem comes as following: (padata_do_parallel) | rcu_read_lock_bh(); | err = -EINVAL; | (padata_replace) | pinst->flags |= PADATA_RESET; err = -EBUSY | if (pinst->flags & PADATA_RESET) | rcu_read_unlock_bh() | return err
In order to resolve the problem, we replace the return err -EBUSY with -EAGAIN, which means parallel_data is changing, and the caller should call it again.
v3: remove retry and just change the return err. v2: introduce padata_try_do_parallel() in pcrypt_aead_encrypt and pcrypt_aead_decrypt to solve the hungtask.(CVE-2023-52813)

Input: synaptics-rmi4 - fix use after free in rmi_unregister_function()
The put_device() calls rmi_release_function() which frees "fn" so the dereference on the next line "fn->num_of_irqs" is a use after free. Move the put_device() to the end to fix this.(CVE-2023-52840)
In the Linux kernel, the following vulnerability has been resolved:
media: bttv: fix use after free error due to btv->timeout timer
There may be some a race condition between timer function bttv_irq_timeout and bttv_remove. The timer is setup in probe and there is no timer_delete operation in remove function. When it hit kfree btv, the function might still be invoked, which will cause use after free bug.
This bug is found by static analysis, it may be false positive.
Fix it by adding del_timer_sync invoking to the remove function.

nilfs2: prevent kernel bug at submit_bh_wbc()
Fix a bug where nilfs_get_block() returns a successful status when searching and inserting the specified block both fail inconsistently. If this inconsistent behavior is not due to a previously fixed bug, then an unexpected race is occurring, so return a temporary error -EAGAIN instead.
This prevents callers such as __block_write_begin_int() from requesting a read into a buffer that is not mapped, which would cause the BUG_ON check for the BH_Mapped flag in submit_bh_wbc() to fail.(CVE-2024-26955)
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix failure to detect DAT corruption in btree and direct mappings
Patch series "nilfs2: fix kernel bug at submit_bh_wbc()".
This resolves a kernel BUG reported by syzbot. Since there are two flaws involved, I've made each one a separate patch.
The first patch alone resolves the syzbot-reported bug, but I think both fixes should be sent to stable, so I've tagged them as such.
This patch (of 2):
Syzbot has reported a kernel bug in submit_bh_wbc() when writing file data to a nilfs2 file system whose metadata is corrupted.
There are two flaws involved in this issue.
The first flaw is that when nilfs_get_block() locates a data block using btree or direct mapping, if the disk address translation routine nilfs_dat_translate() fails with internal code -ENOENT due to DAT metadata corruption, it can be passed back to nilfs_get_block(). This causes nilfs_get_block() to misidentify an existing block as non-existent, causing both data block lookup and insertion to fail inconsistently.
The second flaw is that nilfs_get_block() returns a successful status in this inconsistent state. This causes the caller __block_write_begin_int() or others to request a read even though the buffer is not mapped, resulting in a BUG_ON check for the BH_Mapped flag in submit_bh_wbc() failing.
This fixes the first issue by changing the return value to code -EINVAL when a conversion using DAT fails with code -ENOENT, avoiding the conflicting condition that leads to the kernel bug described above. Here, code -EINVAL indicates that metadata corruption was detected during the block lookup, which will be properly handled as a file system error and converted to -EIO when passing through the nilfs2 bmap layer.(CVE-2024-26956)
In the Linux kernel, the following vulnerability has been resolved:
s390/zcrypt: fix reference counting on zcrypt card objects
Tests with hot-plugging crytpo cards on KVM guests with debug kernel build revealed an use after free for the load field of the struct zcrypt_card. The reason was an incorrect reference handling of the zcrypt card object which could lead to a free of the zcrypt card object while it was still in use.

This is because we're completing the nfs_direct_request twice in a row.
The source of this is when we have our commit requests to submit, we process them and send them off, and then in the completion path for the commit requests we have
if (nfs_commit_end(cinfo.mds)) nfs_direct_write_complete(dreq);
However since we're submitting asynchronous requests we sometimes have one that completes before we submit the next one, so we end up calling complete on the nfs_direct_request twice.
The only other place we use nfs_generic_commit_list() is in __nfs_commit_inode, which wraps this call in a
nfs_commit_begin(); nfs_commit_end();
Which is a common pattern for this style of completion handling, one that is also repeated in the direct code with get_dreq()/put_dreq() calls around where we process events as well as in the completion paths.
Fix this by using the same pattern for the commit requests.

mm: swap: fix race between free_swap_and_cache() and swapoff()
There was previously a theoretical window where swapoff() could run and teardown a swap_info_struct while a call to free_swap_and_cache() was running in another thread. This could cause, amongst other bad possibilities, swap_page_trans_huge_swapped() (called by free_swap_and_cache()) to access the freed memory for swap_map.
This is a theoretical problem and I haven't been able to provoke it from a test case. But there has been agreement based on code review that this is possible (see link below).
Fix it by using get_swap_device()/put_swap_device(), which will stall swapoff(). There was an extra check in _swap_info_get() to confirm that the swap entry was not free. This isn't present in get_swap_device() because it doesn't make sense in general due to the race between getting the reference and swapoff. So I've added an equivalent check directly in free_swap_and_cache().
Details of how to provoke one possible issue (thanks to David Hildenbrand for deriving this):
--8<-----
__swap_entry_free() might be the last user and result in "count == SWAP_HAS_CACHE".
swapoff->try_to_unuse() will stop as soon as soon as si->inuse_pages==0.
So the question is: could someone reclaim the folio and turn si->inuse_pages==0, before we completed swap_page_trans_huge_swapped().
Imagine the following: 2 MiB folio in the swapcache. Only 2 subpages are still references by swap entries.
Process 1 still references subpage 0 via swap entry. Process 2 still references subpage 1 via swap entry.
Process 1 quits. Calls free_swap_and_cache(). -> count == SWAP_HAS_CACHE [then, preempted in the hypervisor etc.]
Process 2 quits. Calls free_swap_and_cache(). -> count == SWAP_HAS_CACHE
Process 2 goes ahead, passes swap_page_trans_huge_swapped(), and calls __try_to_reclaim_swap().
__try_to_reclaim_swap()->folio_free_swap()->delete_from_swap_cache()-> put_swap_folio()->free_swap_slot()->swapcache_free_entries()-> swap_entry_free()->swap_range_free()-> ... WRITE_ONCE(si->inuse_pages, si->inuse_pages - nr_entries);
What stops swapoff to succeed after process 2 reclaimed the swap cache but before process1 finished its call to swap_page_trans_huge_swapped()?

crypto: qat - resolve race condition during AER recovery
During the PCI AER system's error recovery process, the kernel driver may encounter a race condition with freeing the reset_data structure's memory. If the device restart will take more than 10 seconds the function scheduling that restart will exit due to a timeout, and the reset_data structure will be freed. However, this data structure is used for completion notification after the restart is completed, which leads to a UAF bug.
This results in a KFENCE bug notice.
BUG: KFENCE: use-after-free read in adf_device_reset_worker+0x38/0xa0 [intel_qat] Use-after-free read at 0x00000000bc56fddf (in kfence-#142): adf_device_reset_worker+0x38/0xa0 [intel_qat] process_one_work+0x173/0x340
To resolve this race condition, the memory associated to the container of the work_struct is freed on the worker if the timeout expired, otherwise on the function that schedules the worker. The timeout detection can be done by checking if the caller is still waiting for completion or not by using completion_done() function.(CVE-2024-26974)

KVM: Always flush async #PF workqueue when vCPU is being destroyed
Always flush the per-vCPU async #PF workqueue when a vCPU is clearing its completion queue, e.g. when a VM and all its vCPUs is being destroyed. KVM must ensure that none of its workqueue callbacks is running when the last reference to the KVM module is put. Gifting a reference to the associated VM prevents the workqueue callback from dereferencing freed vCPU/VM memory, but does not prevent the KVM module from being unloaded before the callback completes.
Drop the misguided VM refcount gifting, as calling kvm_put_kvm() from async_pf_execute() if kvm_put_kvm() flushes the async #PF workqueue will result in deadlock. async_pf_execute() can't return until kvm_put_kvm() finishes, and kvm_put_kvm() can't return until async_pf_execute() finishes:

If kvm_clear_async_pf_completion_queue() actually flushes the workqueue, then there's no need to gift async_pf_execute() a reference because all invocations of async_pf_execute() will be forced to complete before the vCPU and its VM are destroyed/freed. And that in turn fixes the module unloading bug as __fput() won't do module_put() on the last vCPU reference until the vCPU has been freed, e.g. if closing the vCPU file also puts the last reference to the KVM module.
Note that kvm_check_async_pf_completion() may also take the work item off the completion queue and so also needs to flush the work queue, as the work will not be seen by kvm_clear_async_pf_completion_queue(). Waiting on the workqueue could theoretically delay a vCPU due to waiting for the work to complete, but that's a very, very small chance, and likely a very small delay. kvm_arch_async_page_present_queued() unconditionally makes a new request, i.e. will effectively delay entering the guest, so the remaining work is really just:
trace_kvm_async_pf_completed(addr, cr2_or_gpa);
__kvm_vcpu_wake_up(vcpu);
mmput(mm);
and mmput() can't drop the last reference to the page tables if the vCPU is still alive, i.e. the vCPU won't get stuck tearing down page tables.
Add a helper to do the flushing, specifically to deal with "wakeup all" work items, as they aren't actually work items, i.e. are never placed in a workqueue. Trying to flush a bogus workqueue entry rightly makes __flush_work() complain (kudos to whoever added that sanity check).

In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix OOB in nilfs_set_de_type
The size of the nilfs_type_by_mode array in the fs/nilfs2/dir.c file is defined as "S_IFMT >> S_SHIFT", but the nilfs_set_de_type() function, which uses this array, specifies the index to read from the array in the same way as "(mode & S_IFMT) >> S_SHIFT".
static void nilfs_set_de_type(struct nilfs_dir_entry de, struct inode inode) { umode_t mode = inode->i_mode;
de->file_type = nilfs_type_by_mode[(mode & S_IFMT)>>S_SHIFT]; // oob
}
However, when the index is determined this way, an out-of-bounds (OOB) error occurs by referring to an index that is 1 larger than the array size when the condition "mode & S_IFMT == S_IFMT" is satisfied. Therefore, a patch to resize the nilfs_type_by_mode array should be applied to prevent OOB errors.(CVE-2024-26981)
In the Linux kernel, the following vulnerability has been resolved:
Squashfs: check the inode number is not the invalid value of zero
Syskiller has produced an out of bounds access in fill_meta_index().
That out of bounds access is ultimately caused because the inode has an inode number with the invalid value of zero, which was not checked.
The reason this causes the out of bounds access is due to following sequence of events:
-
Fill_meta_index() is called to allocate (via empty_meta_index()) and fill a metadata index. It however suffers a data read error and aborts, invalidating the newly returned empty metadata index. It does this by setting the inode number of the index to zero, which means unused (zero is not a valid inode number).
-
When fill_meta_index() is subsequently called again on another read operation, locate_meta_index() returns the previous index because it matches the inode number of 0. Because this index has been returned it is expected to have been filled, and because it hasn't been, an out of bounds access is performed.
This patch adds a sanity check which checks that the inode number is not zero when the inode is created and returns -EINVAL if it is.

fs: sysfs: Fix reference leak in sysfs_break_active_protection()
The sysfs_break_active_protection() routine has an obvious reference leak in its error path. If the call to kernfs_find_and_get() fails then kn will be NULL, so the companion sysfs_unbreak_active_protection() routine won't get called (and would only cause an access violation by trying to dereference kn->parent if it was called). As a result, the reference to kobj acquired at the start of the function will never be released.
Fix the leak by adding an explicit kobject_put() call when kn is NULL.(CVE-2024-26993)

usb: gadget: f_ncm: Fix UAF ncm object at re-bind after usb ep transport error
When ncm function is working and then stop usb0 interface for link down, eth_stop() is called. At this piont, accidentally if usb transport error should happen in usb_ep_enable(), 'in_ep' and/or 'out_ep' may not be enabled.
After that, ncm_disable() is called to disable for ncm unbind but gether_disconnect() is never called since 'in_ep' is not enabled.
As the result, ncm object is released in ncm unbind but 'dev->port_usb' associated to 'ncm->port' is not NULL.
And when ncm bind again to recover netdev, ncm object is reallocated but usb0 interface is already associated to previous released ncm object.
Therefore, once usb0 interface is up and eth_start_xmit() is called, released ncm object is dereferrenced and it might cause use-after-free memory.

This patch addresses the issue by checking if 'ncm->netdev' is not NULL at ncm_disable() to call gether_disconnect() to deassociate 'dev->port_usb'. It's more reasonable to check 'ncm->netdev' to call gether_connect/disconnect rather than check 'ncm->port.in_ep->enabled' since it might not be enabled but the gether connection might be established.(CVE-2024-26996)

serial/pmac_zilog: Remove flawed mitigation for rx irq flood
The mitigation was intended to stop the irq completely. That may be better than a hard lock-up but it turns out that you get a crash anyway if you're using pmac_zilog as a serial console:
ttyPZ0: pmz: rx irq flood ! BUG: spinlock recursion on CPU#0, swapper/0
That's because the pr_err() call in pmz_receive_chars() results in pmz_console_write() attempting to lock a spinlock already locked in pmz_interrupt(). With CONFIG_DEBUG_SPINLOCK=y, this produces a fatal BUG splat. The spinlock in question is the one in struct uart_port.
Even when it's not fatal, the serial port rx function ceases to work. Also, the iteration limit doesn't play nicely with QEMU, as can be seen in the bug report linked below.

netfilter: nf_tables: fix memleak in map from abort path
The delete set command does not rely on the transaction object for element removal, therefore, a combination of delete element + delete set from the abort path could result in restoring twice the refcount of the mapping.
Check for inactive element in the next generation for the delete element command in the abort path, skip restoring state if next generation bit has been already cleared. This is similar to the activate logic using the set walk iterator.

In the Linux kernel, the following vulnerability has been resolved:
spi: spi-mt65xx: Fix NULL pointer access in interrupt handler
The TX buffer in spi_transfer can be a NULL pointer, so the interrupt handler may end up writing to the invalid memory and cause crashes.
Add a check to trans->tx_buf before using it.(CVE-2024-27028)
In the Linux kernel, the following vulnerability has been resolved:
clk: zynq: Prevent null pointer dereference caused by kmalloc failure
The kmalloc() in zynq_clk_setup() will return null if the physical memory has run out. As a result, if we use snprintf() to write data to the null address, the null pointer dereference bug will happen.
This patch uses a stack variable to replace the kmalloc().(CVE-2024-27037)
In the Linux kernel, the following vulnerability has been resolved:
nfp: flower: handle acti_netdevs allocation failure
The kmalloc_array() in nfp_fl_lag_do_work() will return null, if the physical memory has run out. As a result, if we dereference the acti_netdevs, the null pointer dereference bugs will happen.
This patch adds a check to judge whether allocation failure occurs. If it happens, the delayed work will be rescheduled and try again.(CVE-2024-27046)
In the Linux kernel, the following vulnerability has been resolved:
cpufreq: brcmstb-avs-cpufreq: add check for cpufreq_cpu_get's return value
cpufreq_cpu_get may return NULL. To avoid NULL-dereference check it and return 0 in case of error.

In the Linux kernel, the following vulnerability has been resolved:
s390/dasd: fix double module refcount decrement
Once the discipline is associated with the device, deleting the device takes care of decrementing the module's refcount. Doing it manually on this error path causes refcount to artificially decrease on each error while it should just stay the same.(CVE-2024-27054)
In the Linux kernel, the following vulnerability has been resolved:
USB: usb-storage: Prevent divide-by-0 error in isd200_ata_command
The isd200 sub-driver in usb-storage uses the HEADS and SECTORS values in the ATA ID information to calculate cylinder and head values when creating a CDB for READ or WRITE commands. The calculation involves division and modulus operations, which will cause a crash if either of these values is 0. While this never happens with a genuine device, it could happen with a flawed or subversive emulation, as reported by the syzbot fuzzer.
Protect against this possibility by refusing to bind to the device if either the ATA_ID_HEADS or ATA_ID_SECTORS value in the device's ID information is 0. This requires isd200_Initialization() to return a negative error code when initialization fails; currently it always returns 0 (even when there is an error).(CVE-2024-27059)

In the Linux kernel, the following vulnerability has been resolved:
media: v4l2-tpg: fix some memleaks in tpg_alloc
In tpg_alloc, resources should be deallocated in each and every error-handling paths, since they are allocated in for statements. Otherwise there would be memleaks because tpg_free is called only when tpg_alloc return 0.(CVE-2024-27078)
In the Linux kernel, the following vulnerability has been resolved:

In the Linux kernel, the following vulnerability has been resolved:
ipv6: Fix infinite recursion in fib6_dump_done().
syzkaller reported infinite recursive calls of fib6_dump_done() during netlink socket destruction. [1]
From the log, syzkaller sent an AF_UNSPEC RTM_GETROUTE message, and then the response was generated. The following recvmmsg() resumed the dump for IPv6, but the first call of inet6_dump_fib() failed at kzalloc() due to the fault injection. [0]
12:01:34 executing program 3: r0 = socket$nl_route(0x10, 0x3, 0x0) sendmsg$nl_route(r0, ... snip ...) recvmmsg(r0, ... snip ...) (fail_nth: 8)
Here, fib6_dump_done() was set to nlk_sk(sk)->cb.done, and the next call of inet6_dump_fib() set it to nlk_sk(sk)->cb.args[3]. syzkaller stopped receiving the response halfway through, and finally netlink_sock_destruct() called nlk_sk(sk)->cb.done().
fib6_dump_done() calls fib6_dump_end() and nlk_sk(sk)->cb.done() if it is still not NULL. fib6_dump_end() rewrites nlk_sk(sk)->cb.done() by nlk_sk(sk)->cb.args[3], but it has the same function, not NULL, calling itself recursively and hitting the stack guard page.

In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: Fix potential data-race in __nft_flowtable_type_get()
nft_unregister_flowtable_type() within nf_flow_inet_module_exit() can concurrent with __nft_flowtable_type_get() within nf_tables_newflowtable(). And thhere is not any protection when iterate over nf_tables_flowtables list in __nft_flowtable_type_get(). Therefore, there is pertential data-race of nf_tables_flowtables list entry.
Use list_for_each_entry_rcu() to iterate over nf_tables_flowtables list in __nft_flowtable_type_get(), and use rcu_read_lock() in the caller nft_flowtable_type_get() to protect the entire type query process.(CVE-2024-35898)
In the Linux kernel, the following vulnerability has been resolved:
fbmon: prevent division by zero in fb_videomode_from_videomode()
The expression htotal * vtotal can have a zero value on overflow. It is necessary to prevent division by zero like in fb_var_to_videomode().
Found by Linux Verification Center (linuxtesting.org) with Svace.(CVE-2024-35922)
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix possible memory leak in lpfc_rcv_padisc()
The call to lpfc_sli4_resume_rpi() in lpfc_rcv_padisc() may return an unsuccessful status. In such cases, the elsiocb is not issued, the completion is not called, and thus the elsiocb resource is leaked.
Check return value after calling lpfc_sli4_resume_rpi() and conditionally release the elsiocb resource.(CVE-2024-35930)
In the Linux kernel, the following vulnerability has been resolved:
btrfs: handle chunk tree lookup error in btrfs_relocate_sys_chunks()
The unhandled case in btrfs_relocate_sys_chunks() loop is a corruption, as it could be caused only by two impossible conditions:
-
at first the search key is set up to look for a chunk tree item, with offset -1, this is an inexact search and the key->offset will contain the correct offset upon a successful search, a valid chunk tree item cannot have an offset -1
-
after first successful search, the found_key corresponds to a chunk item, the offset is decremented by 1 before the next loop, it's impossible to find a chunk item there due to alignment and size constraints(CVE-2024-35936)
In the Linux kernel, the following vulnerability has been resolved:
drm/client: Fully protect modes[] with dev->mode_config.mutex
The modes[] array contains pointers to modes on the connectors' mode lists, which are protected by dev->mode_config.mutex. Thus we need to extend modes[] the same protection or by the time we use it the elements may already be pointing to freed/reused memory.(CVE-2024-35950)

In the Linux kernel, the following vulnerability has been resolved:
HID: i2c-hid: remove I2C_HID_READ_PENDING flag to prevent lock-up
The flag I2C_HID_READ_PENDING is used to serialize I2C operations. However, this is not necessary, because I2C core already has its own locking for that.
More importantly, this flag can cause a lock-up: if the flag is set in i2c_hid_xfer() and an interrupt happens, the interrupt handler (i2c_hid_irq) will check this flag and return immediately without doing anything, then the interrupt handler will be invoked again in an infinite loop.
Since interrupt handler is an RT task, it takes over the CPU and the flag-clearing task never gets scheduled, thus we have a lock-up.
Delete this unnecessary flag.(CVE-2024-35997)

This causes\nnilfs_get_block() to misidentify an existing block as non-existent,\ncausing both data block lookup and insertion to fail inconsistently.\r\n\r\nThe second flaw is that nilfs_get_block() returns a successful status in\nthis inconsistent state. This causes the caller __block_write_begin_int()\nor others to request a read even though the buffer is not mapped,\nresulting in a BUG_ON check for the BH_Mapped flag in submit_bh_wbc()\nfailing.\r\n\r\nThis fixes the first issue by changing the return value to code -EINVAL\nwhen a conversion using DAT fails with code -ENOENT, avoiding the\nconflicting condition that leads to the kernel bug described above.

This could cause, amongst other bad\npossibilities, swap_page_trans_huge_swapped() (called by\nfree_swap_and_cache()) to access the freed memory for swap_map.\r\n\r\nThis is a theoretical problem and I haven\u0026apos;t been able to provoke it from a\ntest case. But there has been agreement based on code review that this is\npossible (see link below).\r\n\r\nFix it by using get_swap_device()/put_swap_device(), which will stall\nswapoff(). There was an extra check in _swap_info_get() to confirm that\nthe swap entry was not free. This isn\u0026apos;t present in get_swap_device()\nbecause it doesn\u0026apos;t make sense in general due to the race between getting\nthe reference and swapoff.

Therefore, a\npatch to resize the nilfs_type_by_mode array should be applied to prevent\nOOB errors.(CVE-2024-26981)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nSquashfs: check the inode number is not the invalid value of zero\r\n\r\nSyskiller has produced an out of bounds access in fill_meta_index().\r\n\r\nThat out of bounds access is ultimately caused because the inode\nhas an inode number with the invalid value of zero, which was not checked.\r\n\r\nThe reason this causes the out of bounds access is due to following\nsequence of events:\r\n\r\n1. Fill_meta_index() is called to allocate (via empty_meta_index())\n and fill a metadata index. It however suffers a data read error\n and aborts, invalidating the newly returned empty metadata index.\n It does this by setting the inode number of the index to zero,\n which means unused (zero is not a valid inode number).\r\n\r\n2. When fill_meta_index() is subsequently called again on another\n read operation, locate_meta_index() returns the previous index\n because it matches the inode number of 0. Because this index\n has been returned it is expected to have been filled, and because\n it hasn\u0026apos;t been, an out of bounds access is performed.\r\n\r\nThis patch adds a sanity check which checks that the inode number\nis not zero when the inode is created and returns -EINVAL if it is.\r\n\r\n[phillip@squashfs.org.uk: whitespace fix]\n Link: https://lkml.kernel.org/r/20240409204723.446925-1-phillip@squashfs.org.uk(CVE-2024-26982)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nfs: sysfs: Fix reference leak in sysfs_break_active_protection()\r\n\r\nThe sysfs_break_active_protection() routine has an obvious reference\nleak in its error path.

Vulnerability from osv_openeuler – Published: 2024-05-31 11:07 – Updated: 2026-08-06 11:07 – Source websiteThe Linux Kernel, the operating system core itself.
Security Fix(es):
In the Linux kernel, the following vulnerability has been resolved:
usb: dwc3: ep0: fix NULL pointer exception
There is no validation of the index from dwc3_wIndex_to_dep() and we might be referring a non-existing ep and trigger a NULL pointer exception. In certain configurations we might use fewer eps and the index might wrongly indicate a larger ep index than existing.
By adding this validation from the patch we can actually report a wrong index back to the caller.
In our usecase we are using a composite device on an older kernel, but upstream might use this fix also. Unfortunately, I cannot describe the hardware for others to reproduce the issue as it is a proprietary implementation.

In the Linux kernel, the following vulnerability has been resolved:
isdn: mISDN: netjet: Fix crash in nj_probe:
'nj_setup' in netjet.c might fail with -EIO and in this case 'card->irq' is initialized and is bigger than zero. A subsequent call to 'nj_release' will free the irq that has not been requested.
Fix this bug by deleting the previous assignment to 'card->irq' and just keep the assignment before 'request_irq'.

The root cause is multi f2fs filesystem instances can race on accessing global fsync_entry_slab pointer, result in use-after-free issue of slab cache, fixes to init/destroy this slab cache only once during module init/destroy procedure to avoid this issue.(CVE-2021-47335)
In the Linux kernel, the following vulnerability has been resolved:
hwmon: (mlxreg-fan) Return non-zero value when fan current state is enforced from sysfs
Fan speed minimum can be enforced from sysfs. For example, setting current fan speed to 20 is used to enforce fan speed to be at 100% speed, 19 - to be not below 90% speed, etcetera. This feature provides ability to limit fan speed according to some system wise considerations, like absence of some replaceable units or high system ambient temperature.
Request for changing fan minimum speed is configuration request and can be set only through 'sysfs' write procedure. In this situation value of argument 'state' is above nominal fan speed maximum.
Return non-zero code in this case to avoid thermal_cooling_device_stats_update() call, because in this case statistics update violates thermal statistics table range. The issues is observed in case kernel is configured with option CONFIG_THERMAL_STATISTICS.

nvmem: Fix shift-out-of-bound (UBSAN) with byte size cells
If a cell has 'nbits' equal to a multiple of BITS_PER_BYTE the logic
*p &= GENMASK((cell->nbits%BITS_PER_BYTE) - 1, 0);
will become undefined behavior because nbits modulo BITS_PER_BYTE is 0, and we subtract one from that making a large number that is then shifted more than the number of bits that fit into an unsigned long.

ALSA: emu10k1: Fix out of bounds access in snd_emu10k1_pcm_channel_alloc()
The voice allocator sometimes begins allocating from near the end of the array and then wraps around, however snd_emu10k1_pcm_channel_alloc() accesses the newly allocated voices as if it never wrapped around.
This results in out of bounds access if the first voice has a high enough index so that first_voice + requested_voice_count > NUM_G (64). The more voices are requested, the more likely it is for this to occur.
This was initially discovered using PipeWire, however it can be reproduced by calling aplay multiple times with 16 channels: aplay -r 48000 -D plughw:CARD=Live,DEV=3 -c 16 /dev/zero

In the Linux kernel, the following vulnerability has been resolved:
NTB: fix possible name leak in ntb_register_device()
If device_register() fails in ntb_register_device(), the device name allocated by dev_set_name() should be freed. As per the comment in device_register(), callers should use put_device() to give up the reference in the error path. So fix this by calling put_device() in the error path so that the name can be freed in kobject_cleanup().
As a result of this, put_device() in the error path of ntb_register_device() is removed and the actual error is returned.

In persistent_ram_init_ecc(), on 64-bit arches DIV_ROUND_UP() will return 64-bit value since persistent_ram_zone::buffer_size has type size_t which is derived from the 64-bit unsigned long, while the ecc_blocks variable this value gets assigned to has (always 32-bit) int type. Even if that value fits into int type, an overflow is still possible when calculating the size_t typed ecc_total variable further below since there's no cast to any 64-bit type before multiplication.

drm/amd/pm: fix a double-free in si_dpm_init
When the allocation of adev->pm.dpm.dyn_state.vddc_dependency_on_dispclk.entries fails, amdgpu_free_extended_power_table is called to free some fields of adev. However, when the control flow returns to si_dpm_sw_init, it goes to label dpm_failed and calls si_dpm_fini, which calls amdgpu_free_extended_power_table again and free those fields again. Thus a double-free is triggered.(CVE-2023-52691)

If IPv6 support is disabled at boot (ipv6.disable=1), the calipso_init() -> netlbl_calipso_ops_register() function isn't called, and the netlbl_calipso_ops_get() function always returns NULL. In this case, the netlbl_calipso_add_pass() function allocates memory for the doi_def variable but doesn't free it with the calipso_doi_free().

Fix a bug where nilfs_get_block() returns a successful status when searching and inserting the specified block both fail inconsistently. If this inconsistent behavior is not due to a previously fixed bug, then an unexpected race is occurring, so return a temporary error -EAGAIN instead.
This prevents callers such as __block_write_begin_int() from requesting a read into a buffer that is not mapped, which would cause the BUG_ON check for the BH_Mapped flag in submit_bh_wbc() to fail.(CVE-2024-26955)
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix failure to detect DAT corruption in btree and direct mappings
Patch series "nilfs2: fix kernel bug at submit_bh_wbc()".
This resolves a kernel BUG reported by syzbot. Since there are two flaws involved, I've made each one a separate patch.
The first patch alone resolves the syzbot-reported bug, but I think both fixes should be sent to stable, so I've tagged them as such.
This patch (of 2):
Syzbot has reported a kernel bug in submit_bh_wbc() when writing file data to a nilfs2 file system whose metadata is corrupted.
There are two flaws involved in this issue.
The first flaw is that when nilfs_get_block() locates a data block using btree or direct mapping, if the disk address translation routine nilfs_dat_translate() fails with internal code -ENOENT due to DAT metadata corruption, it can be passed back to nilfs_get_block(). This causes nilfs_get_block() to misidentify an existing block as non-existent, causing both data block lookup and insertion to fail inconsistently.
The second flaw is that nilfs_get_block() returns a successful status in this inconsistent state. This causes the caller __block_write_begin_int() or others to request a read even though the buffer is not mapped, resulting in a BUG_ON check for the BH_Mapped flag in submit_bh_wbc() failing.
This fixes the first issue by changing the return value to code -EINVAL when a conversion using DAT fails with code -ENOENT, avoiding the conflicting condition that leads to the kernel bug described above. Here, code -EINVAL indicates that metadata corruption was detected during the block lookup, which will be properly handled as a file system error and converted to -EIO when passing through the nilfs2 bmap layer.(CVE-2024-26956)

s390/zcrypt: fix reference counting on zcrypt card objects
Tests with hot-plugging crytpo cards on KVM guests with debug kernel build revealed an use after free for the load field of the struct zcrypt_card. The reason was an incorrect reference handling of the zcrypt card object which could lead to a free of the zcrypt card object while it was still in use.

This is because we're completing the nfs_direct_request twice in a row.
The source of this is when we have our commit requests to submit, we process them and send them off, and then in the completion path for the commit requests we have
if (nfs_commit_end(cinfo.mds)) nfs_direct_write_complete(dreq);
However since we're submitting asynchronous requests we sometimes have one that completes before we submit the next one, so we end up calling complete on the nfs_direct_request twice.
The only other place we use nfs_generic_commit_list() is in __nfs_commit_inode, which wraps this call in a
nfs_commit_begin(); nfs_commit_end();
Which is a common pattern for this style of completion handling, one that is also repeated in the direct code with get_dreq()/put_dreq() calls around where we process events as well as in the completion paths.
Fix this by using the same pattern for the commit requests.

mm: swap: fix race between free_swap_and_cache() and swapoff()
There was previously a theoretical window where swapoff() could run and teardown a swap_info_struct while a call to free_swap_and_cache() was running in another thread. This could cause, amongst other bad possibilities, swap_page_trans_huge_swapped() (called by free_swap_and_cache()) to access the freed memory for swap_map.
This is a theoretical problem and I haven't been able to provoke it from a test case. But there has been agreement based on code review that this is possible (see link below).
Fix it by using get_swap_device()/put_swap_device(), which will stall swapoff(). There was an extra check in _swap_info_get() to confirm that the swap entry was not free. This isn't present in get_swap_device() because it doesn't make sense in general due to the race between getting the reference and swapoff. So I've added an equivalent check directly in free_swap_and_cache().
Details of how to provoke one possible issue (thanks to David Hildenbrand for deriving this):
--8<-----
__swap_entry_free() might be the last user and result in "count == SWAP_HAS_CACHE".
swapoff->try_to_unuse() will stop as soon as soon as si->inuse_pages==0.
So the question is: could someone reclaim the folio and turn si->inuse_pages==0, before we completed swap_page_trans_huge_swapped().
Imagine the following: 2 MiB folio in the swapcache. Only 2 subpages are still references by swap entries.
Process 1 still references subpage 0 via swap entry. Process 2 still references subpage 1 via swap entry.
Process 1 quits. Calls free_swap_and_cache(). -> count == SWAP_HAS_CACHE [then, preempted in the hypervisor etc.]
Process 2 quits. Calls free_swap_and_cache(). -> count == SWAP_HAS_CACHE
Process 2 goes ahead, passes swap_page_trans_huge_swapped(), and calls __try_to_reclaim_swap().
__try_to_reclaim_swap()->folio_free_swap()->delete_from_swap_cache()-> put_swap_folio()->free_swap_slot()->swapcache_free_entries()-> swap_entry_free()->swap_range_free()-> ... WRITE_ONCE(si->inuse_pages, si->inuse_pages - nr_entries);
What stops swapoff to succeed after process 2 reclaimed the swap cache but before process1 finished its call to swap_page_trans_huge_swapped()?

crypto: qat - resolve race condition during AER recovery
During the PCI AER system's error recovery process, the kernel driver may encounter a race condition with freeing the reset_data structure's memory. If the device restart will take more than 10 seconds the function scheduling that restart will exit due to a timeout, and the reset_data structure will be freed. However, this data structure is used for completion notification after the restart is completed, which leads to a UAF bug.
This results in a KFENCE bug notice.

To resolve this race condition, the memory associated to the container of the work_struct is freed on the worker if the timeout expired, otherwise on the function that schedules the worker. The timeout detection can be done by checking if the caller is still waiting for completion or not by using completion_done() function.(CVE-2024-26974)

KVM: Always flush async #PF workqueue when vCPU is being destroyed
Always flush the per-vCPU async #PF workqueue when a vCPU is clearing its completion queue, e.g. when a VM and all its vCPUs is being destroyed. KVM must ensure that none of its workqueue callbacks is running when the last reference to the KVM module is put. Gifting a reference to the associated VM prevents the workqueue callback from dereferencing freed vCPU/VM memory, but does not prevent the KVM module from being unloaded before the callback completes.
Drop the misguided VM refcount gifting, as calling kvm_put_kvm() from async_pf_execute() if kvm_put_kvm() flushes the async #PF workqueue will result in deadlock. async_pf_execute() can't return until kvm_put_kvm() finishes, and kvm_put_kvm() can't return until async_pf_execute() finishes:

If kvm_clear_async_pf_completion_queue() actually flushes the workqueue, then there's no need to gift async_pf_execute() a reference because all invocations of async_pf_execute() will be forced to complete before the vCPU and its VM are destroyed/freed. And that in turn fixes the module unloading bug as __fput() won't do module_put() on the last vCPU reference until the vCPU has been freed, e.g. if closing the vCPU file also puts the last reference to the KVM module.
Note that kvm_check_async_pf_completion() may also take the work item off the completion queue and so also needs to flush the work queue, as the work will not be seen by kvm_clear_async_pf_completion_queue(). Waiting on the workqueue could theoretically delay a vCPU due to waiting for the work to complete, but that's a very, very small chance, and likely a very small delay. kvm_arch_async_page_present_queued() unconditionally makes a new request, i.e. will effectively delay entering the guest, so the remaining work is really just:
trace_kvm_async_pf_completed(addr, cr2_or_gpa);
__kvm_vcpu_wake_up(vcpu);
mmput(mm);
and mmput() can't drop the last reference to the page tables if the vCPU is still alive, i.e. the vCPU won't get stuck tearing down page tables.
Add a helper to do the flushing, specifically to deal with "wakeup all" work items, as they aren't actually work items, i.e. are never placed in a workqueue. Trying to flush a bogus workqueue entry rightly makes __flush_work() complain (kudos to whoever added that sanity check).

nilfs2: fix OOB in nilfs_set_de_type
The size of the nilfs_type_by_mode array in the fs/nilfs2/dir.c file is defined as "S_IFMT >> S_SHIFT", but the nilfs_set_de_type() function, which uses this array, specifies the index to read from the array in the same way as "(mode & S_IFMT) >> S_SHIFT".
static void nilfs_set_de_type(struct nilfs_dir_entry de, struct inode inode) { umode_t mode = inode->i_mode;
de->file_type = nilfs_type_by_mode[(mode & S_IFMT)>>S_SHIFT]; // oob
}
However, when the index is determined this way, an out-of-bounds (OOB) error occurs by referring to an index that is 1 larger than the array size when the condition "mode & S_IFMT == S_IFMT" is satisfied. Therefore, a patch to resize the nilfs_type_by_mode array should be applied to prevent OOB errors.(CVE-2024-26981)
In the Linux kernel, the following vulnerability has been resolved:
Squashfs: check the inode number is not the invalid value of zero
Syskiller has produced an out of bounds access in fill_meta_index().
That out of bounds access is ultimately caused because the inode has an inode number with the invalid value of zero, which was not checked.
The reason this causes the out of bounds access is due to following sequence of events:
-
Fill_meta_index() is called to allocate (via empty_meta_index()) and fill a metadata index. It however suffers a data read error and aborts, invalidating the newly returned empty metadata index. It does this by setting the inode number of the index to zero, which means unused (zero is not a valid inode number).
-
When fill_meta_index() is subsequently called again on another read operation, locate_meta_index() returns the previous index because it matches the inode number of 0. Because this index has been returned it is expected to have been filled, and because it hasn't been, an out of bounds access is performed.
This patch adds a sanity check which checks that the inode number is not zero when the inode is created and returns -EINVAL if it is.

As a result, the reference to kobj acquired at the start of the function will never be released.
Fix the leak by adding an explicit kobject_put() call when kn is NULL.(CVE-2024-26993)

In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_ncm: Fix UAF ncm object at re-bind after usb ep transport error
When ncm function is working and then stop usb0 interface for link down, eth_stop() is called. At this piont, accidentally if usb transport error should happen in usb_ep_enable(), 'in_ep' and/or 'out_ep' may not be enabled.
After that, ncm_disable() is called to disable for ncm unbind but gether_disconnect() is never called since 'in_ep' is not enabled.
As the result, ncm object is released in ncm unbind but 'dev->port_usb' associated to 'ncm->port' is not NULL.
And when ncm bind again to recover netdev, ncm object is reallocated but usb0 interface is already associated to previous released ncm object.
Therefore, once usb0 interface is up and eth_start_xmit() is called, released ncm object is dereferrenced and it might cause use-after-free memory.
[function unlink via configfs] usb0: eth_stop dev->port_usb=ffffff9b179c3200 --> error happens in usb_ep_enable(). NCM: ncm_disable: ncm=ffffff9b179c3200 --> no gether_disconnect() since ncm->port.in_ep->enabled is false. NCM: ncm_unbind: ncm unbind ncm=ffffff9b179c3200 NCM: ncm_free: ncm free ncm=ffffff9b179c3200 <-- released ncm
[function link via configfs] NCM: ncm_alloc: ncm alloc ncm=ffffff9ac4f8a000 NCM: ncm_bind: ncm bind ncm=ffffff9ac4f8a000 NCM: ncm_set_alt: ncm=ffffff9ac4f8a000 alt=0 usb0: eth_open dev->port_usb=ffffff9b179c3200 <-- previous released ncm usb0: eth_start dev->port_usb=ffffff9b179c3200 <-- eth_start_xmit() --> dev->wrap() Unable to handle kernel paging request at virtual address dead00000000014f
This patch addresses the issue by checking if 'ncm->netdev' is not NULL at ncm_disable() to call gether_disconnect() to deassociate 'dev->port_usb'. It's more reasonable to check 'ncm->netdev' to call gether_connect/disconnect rather than check 'ncm->port.in_ep->enabled' since it might not be enabled but the gether connection might be established.(CVE-2024-26996)
In the Linux kernel, the following vulnerability has been resolved:
serial/pmac_zilog: Remove flawed mitigation for rx irq flood
The mitigation was intended to stop the irq completely. That may be better than a hard lock-up but it turns out that you get a crash anyway if you're using pmac_zilog as a serial console:
ttyPZ0: pmz: rx irq flood ! BUG: spinlock recursion on CPU#0, swapper/0
That's because the pr_err() call in pmz_receive_chars() results in pmz_console_write() attempting to lock a spinlock already locked in pmz_interrupt(). With CONFIG_DEBUG_SPINLOCK=y, this produces a fatal BUG splat. The spinlock in question is the one in struct uart_port.
Even when it's not fatal, the serial port rx function ceases to work. Also, the iteration limit doesn't play nicely with QEMU, as can be seen in the bug report linked below.
A web search for other reports of the error message "pmz: rx irq flood" didn't produce anything. So I don't think this code is needed any more. Remove it.(CVE-2024-26999)
In the Linux kernel, the following vulnerability has been resolved:
serial: mxs-auart: add spinlock around changing cts state

comedi: vmk80xx: fix incomplete endpoint checking
While vmk80xx does have endpoint checking implemented, some things can fall through the cracks. Depending on the hardware model, URBs can have either bulk or interrupt type, and current version of vmk80xx_find_usb_endpoints() function does not take that fully into account. While this warning does not seem to be too harmful, at the very least it will crash systems with 'panic_on_warn' set on them.
Fix the issue found by Syzkaller [1] by somewhat simplifying the endpoint checking process with usb_find_common_endpoints() and ensuring that only expected endpoint types are present.
This patch has not been tested on real hardware.

USB: usb-storage: Prevent divide-by-0 error in isd200_ata_command
The isd200 sub-driver in usb-storage uses the HEADS and SECTORS values in the ATA ID information to calculate cylinder and head values when creating a CDB for READ or WRITE commands. The calculation involves division and modulus operations, which will cause a crash if either of these values is 0. While this never happens with a genuine device, it could happen with a flawed or subversive emulation, as reported by the syzbot fuzzer.
Protect against this possibility by refusing to bind to the device if either the ATA_ID_HEADS or ATA_ID_SECTORS value in the device's ID information is 0. This requires isd200_Initialization() to return a negative error code when initialization fails; currently it always returns 0 (even when there is an error).(CVE-2024-27059)

In the Linux kernel, the following vulnerability has been resolved:
media: ttpci: fix two memleaks in budget_av_attach
When saa7146_register_device and saa7146_vv_init fails, budget_av_attach should free the resources it allocates, like the error-handling of ttpci_budget_init does. Besides, there are two fixme comment refers to such deallocations.(CVE-2024-27073)
In the Linux kernel, the following vulnerability has been resolved:
media: dvb-frontends: avoid stack overflow warnings with clang
A previous patch worked around a KASAN issue in stv0367, now a similar problem showed up with clang:
drivers/media/dvb-frontends/stv0367.c:1222:12: error: stack frame size (3624) exceeds limit (2048) in 'stv0367ter_set_frontend' [-Werror,-Wframe-larger-than] 1214 | static int stv0367ter_set_frontend(struct dvb_frontend *fe)
Rework the stv0367_writereg() function to be simpler and mark both register access functions as noinline_for_stack so the temporary i2c_msg structures do not get duplicated on the stack when KASAN_STACK is enabled.(CVE-2024-27075)
In the Linux kernel, the following vulnerability has been resolved:
media: v4l2-mem2mem: fix a memleak in v4l2_m2m_register_entity
The entity->name (i.e. name) is allocated in v4l2_m2m_register_entity but isn't freed in its following error-handling paths. This patch adds such deallocation to prevent memleak of entity->name.(CVE-2024-27077)
In the Linux kernel, the following vulnerability has been resolved:
media: v4l2-tpg: fix some memleaks in tpg_alloc
In tpg_alloc, resources should be deallocated in each and every error-handling paths, since they are allocated in for statements. Otherwise there would be memleaks because tpg_free is called only when tpg_alloc return 0.(CVE-2024-27078)
In the Linux kernel, the following vulnerability has been resolved:
SUNRPC: fix some memleaks in gssx_dec_option_array
The creds and oa->data need to be freed in the error-handling paths after their allocation. So this patch add these deallocations in the corresponding paths.(CVE-2024-27388)
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_flow_offload: reset dst in route object after setting up flow
dst is transferred to the flow object, route object does not own it anymore. Reset dst in route object, otherwise if flow_offload_add() fails, error path releases dst twice, leading to a refcount underflow.(CVE-2024-27403)
In the Linux kernel, the following vulnerability has been resolved:
netrom: Fix data-races around sysctl_net_busy_read
We need to protect the reader reading the sysctl value because the value can be changed concurrently.(CVE-2024-27419)

In the Linux kernel, the following vulnerability has been resolved:
dm snapshot: fix lockup in dm_exception_table_exit
There was reported lockup when we exit a snapshot with many exceptions. Fix this by adding "cond_resched" to the loop that frees the exceptions.(CVE-2024-35805)
In the Linux kernel, the following vulnerability has been resolved:
soc: fsl: qbman: Always disable interrupts when taking cgr_lock
smp_call_function_single disables IRQs when executing the callback. To prevent deadlocks, we must disable IRQs when taking cgr_lock elsewhere. This is already done by qman_update_cgr and qman_delete_cgr; fix the other lockers.(CVE-2024-35806)
In the Linux kernel, the following vulnerability has been resolved:
fs/aio: Check IOCB_AIO_RW before the struct aio_kiocb conversion
The first kiocb_set_cancel_fn() argument may point at a struct kiocb that is not embedded inside struct aio_kiocb. With the current code, depending on the compiler, the req->ki_ctx read happens either before the IOCB_AIO_RW test or after that test. Move the req->ki_ctx read such that it is guaranteed that the IOCB_AIO_RW test happens first.(CVE-2024-35815)
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: fix a double-free in arfs_create_groups
When in allocated by kvzalloc fails, arfs_create_groups will free
ft->g and return an error. However, arfs_create_table, the only caller of
arfs_create_groups, will hold this error and call to
mlx5e_destroy_flow_table, in which the ft->g will be freed again.(CVE-2024-35835)
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix information leak in btrfs_ioctl_logical_to_ino()

Bytes 40-65535 of 65536 are uninitialized Memory access of size 65536 starts at ffff888045a40000
This happens, because we're copying a 'struct btrfs_data_container' back to user-space. This btrfs_data_container is allocated in 'init_data_container()' via kvmalloc(), which does not zero-fill the memory.
Fix this by using kvzalloc() which zeroes out the memory on allocation.(CVE-2024-35849)
In the Linux kernel, the following vulnerability has been resolved:
ipv6: Fix infinite recursion in fib6_dump_done().
syzkaller reported infinite recursive calls of fib6_dump_done() during netlink socket destruction. [1]
From the log, syzkaller sent an AF_UNSPEC RTM_GETROUTE message, and then the response was generated. The following recvmmsg() resumed the dump for IPv6, but the first call of inet6_dump_fib() failed at kzalloc() due to the fault injection. [0]
12:01:34 executing program 3: r0 = socket$nl_route(0x10, 0x3, 0x0) sendmsg$nl_route(r0, ... snip ...) recvmmsg(r0, ... snip ...) (fail_nth: 8)
Here, fib6_dump_done() was set to nlk_sk(sk)->cb.done, and the next call of inet6_dump_fib() set it to nlk_sk(sk)->cb.args[3]. syzkaller stopped receiving the response halfway through, and finally netlink_sock_destruct() called nlk_sk(sk)->cb.done().
fib6_dump_done() calls fib6_dump_end() and nlk_sk(sk)->cb.done() if it is still not NULL. fib6_dump_end() rewrites nlk_sk(sk)->cb.done() by nlk_sk(sk)->cb.args[3], but it has the same function, not NULL, calling itself recursively and hitting the stack guard page.
To avoid the issue, let's set the destructor after kzalloc().

In the Linux kernel, the following vulnerability has been resolved:
btrfs: handle chunk tree lookup error in btrfs_relocate_sys_chunks()
The unhandled case in btrfs_relocate_sys_chunks() loop is a corruption, as it could be caused only by two impossible conditions:
-
at first the search key is set up to look for a chunk tree item, with offset -1, this is an inexact search and the key->offset will contain the correct offset upon a successful search, a valid chunk tree item cannot have an offset -1
-
after first successful search, the found_key corresponds to a chunk item, the offset is decremented by 1 before the next loop, it's impossible to find a chunk item there due to alignment and size constraints(CVE-2024-35936)
In the Linux kernel, the following vulnerability has been resolved:

In the Linux kernel, the following vulnerability has been resolved:
HID: i2c-hid: remove I2C_HID_READ_PENDING flag to prevent lock-up
The flag I2C_HID_READ_PENDING is used to serialize I2C operations. However, this is not necessary, because I2C core already has its own locking for that.
More importantly, this flag can cause a lock-up: if the flag is set in i2c_hid_xfer() and an interrupt happens, the interrupt handler (i2c_hid_irq) will check this flag and return immediately without doing anything, then the interrupt handler will be invoked again in an infinite loop.
Since interrupt handler is an RT task, it takes over the CPU and the flag-clearing task never gets scheduled, thus we have a lock-up.
Delete this unnecessary flag.(CVE-2024-35997)

This causes\nnilfs_get_block() to misidentify an existing block as non-existent,\ncausing both data block lookup and insertion to fail inconsistently.\r\n\r\nThe second flaw is that nilfs_get_block() returns a successful status in\nthis inconsistent state. This causes the caller __block_write_begin_int()\nor others to request a read even though the buffer is not mapped,\nresulting in a BUG_ON check for the BH_Mapped flag in submit_bh_wbc()\nfailing.\r\n\r\nThis fixes the first issue by changing the return value to code -EINVAL\nwhen a conversion using DAT fails with code -ENOENT, avoiding the\nconflicting condition that leads to the kernel bug described above.

This could cause, amongst other bad\npossibilities, swap_page_trans_huge_swapped() (called by\nfree_swap_and_cache()) to access the freed memory for swap_map.\r\n\r\nThis is a theoretical problem and I haven\u0026apos;t been able to provoke it from a\ntest case. But there has been agreement based on code review that this is\npossible (see link below).\r\n\r\nFix it by using get_swap_device()/put_swap_device(), which will stall\nswapoff(). There was an extra check in _swap_info_get() to confirm that\nthe swap entry was not free. This isn\u0026apos;t present in get_swap_device()\nbecause it doesn\u0026apos;t make sense in general due to the race between getting\nthe reference and swapoff.

Therefore, a\npatch to resize the nilfs_type_by_mode array should be applied to prevent\nOOB errors.(CVE-2024-26981)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nSquashfs: check the inode number is not the invalid value of zero\r\n\r\nSyskiller has produced an out of bounds access in fill_meta_index().\r\n\r\nThat out of bounds access is ultimately caused because the inode\nhas an inode number with the invalid value of zero, which was not checked.\r\n\r\nThe reason this causes the out of bounds access is due to following\nsequence of events:\r\n\r\n1. Fill_meta_index() is called to allocate (via empty_meta_index())\n and fill a metadata index. It however suffers a data read error\n and aborts, invalidating the newly returned empty metadata index.\n It does this by setting the inode number of the index to zero,\n which means unused (zero is not a valid inode number).\r\n\r\n2. When fill_meta_index() is subsequently called again on another\n read operation, locate_meta_index() returns the previous index\n because it matches the inode number of 0. Because this index\n has been returned it is expected to have been filled, and because\n it hasn\u0026apos;t been, an out of bounds access is performed.\r\n\r\nThis patch adds a sanity check which checks that the inode number\nis not zero when the inode is created and returns -EINVAL if it is.\r\n\r\n[phillip@squashfs.org.uk: whitespace fix]\n Link: https://lkml.kernel.org/r/20240409204723.446925-1-phillip@squashfs.org.uk(CVE-2024-26982)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nfs: sysfs: Fix reference leak in sysfs_break_active_protection()\r\n\r\nThe sysfs_break_active_protection() routine has an obvious reference\nleak in its error path.

OESA-2024-2183 (CVE-2022-48828)
Vulnerability from osv_openeuler – Published: 2024-09-27 11:07 – Updated: 2026-08-06 11:07 – Source websiteThe Linux Kernel, the operating system core itself.
Security Fix(es):
In the Linux kernel, the following vulnerability has been resolved:
NFSD: Fix ia_size underflow
iattr::ia_size is a loff_t, which is a signed 64-bit type. NFSv3 and NFSv4 both define file size as an unsigned 64-bit type. Thus there is a range of valid file size values an NFS client can send that is already larger than Linux can handle.
Currently decode_fattr4() dumps a full u64 value into ia_size. If that value happens to be larger than S64_MAX, then ia_size underflows. I'm about to fix up the NFSv3 behavior as well, so let's catch the underflow in the common code path: nfsd_setattr().(CVE-2022-48828)
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/pm: fix a double-free in si_dpm_init
When the allocation of adev->pm.dpm.dyn_state.vddc_dependency_on_dispclk.entries fails, amdgpu_free_extended_power_table is called to free some fields of adev. However, when the control flow returns to si_dpm_sw_init, it goes to label dpm_failed and calls si_dpm_fini, which calls amdgpu_free_extended_power_table again and free those fields again. Thus a double-free is triggered.(CVE-2023-52691)
In the Linux kernel, the following vulnerability has been resolved:

In the Linux kernel, the following vulnerability has been resolved:
drivers: core: synchronize really_probe() and dev_uevent()
Synchronize the dev->driver usage in really_probe() and dev_uevent(). These can run in different threads, what can result in the following race condition for dev->driver uninitialization:
Thread #1:
really_probe() { ... probe_failed: ... device_unbind_cleanup(dev) { ... dev->driver = NULL; // <= Failed probe sets dev->driver to NULL ... } ... }
Thread #2:
dev_uevent() { ... if (dev->driver) // If dev->driver is NULLed from really_probe() from here on, // after above check, the system crashes add_uevent_var(env, "DRIVER=%s", dev->driver->name); ... }
really_probe() holds the lock, already. So nothing needs to be done there. dev_uevent() is called with lock held, often, too. But not always. What implies that we can't add any locking in dev_uevent() itself. So fix this race by adding the lock to the non-protected path. This is the path where above race is observed:
dev_uevent+0x235/0x380 uevent_show+0x10c/0x1f0 <= Add lock here dev_attr_show+0x3a/0xa0 sysfs_kf_seq_show+0x17c/0x250 kernfs_seq_show+0x7c/0x90 seq_read_iter+0x2d7/0x940 kernfs_fop_read_iter+0xc6/0x310 vfs_read+0x5bc/0x6b0 ksys_read+0xeb/0x1b0 __x64_sys_read+0x42/0x50 x64_sys_call+0x27ad/0x2d30 do_syscall_64+0xcd/0x1d0 entry_SYSCALL_64_after_hwframe+0x77/0x7f
Similar cases are reported by syzkaller in
https://syzkaller.appspot.com/bug?extid=ffa8143439596313a85a
But these are regarding the initialization of dev->driver
dev->driver = drv;
As this switches dev->driver to non-NULL these reports can be considered to be false-positives (which should be "fixed" by this commit, as well, though).
The same issue was reported and tried to be fixed back in 2015 in
https://lore.kernel.org/lkml/1421259054-2574-1-git-send-email-a.sangwan@samsung.com/
already.(CVE-2024-39501)
In the Linux kernel, the following vulnerability has been resolved:
scsi: qedi: Fix crash while reading debugfs attribute
The qedi_dbg_do_not_recover_cmd_read() function invokes sprintf() directly on a __user pointer, which results into the crash.
To fix this issue, use a small local stack buffer for sprintf() and then call simple_read_from_buffer(), which in turns make the copy_to_user() call.

In the Linux kernel, the following vulnerability has been resolved:
nilfs2: add missing check for inode numbers on directory entries
Syzbot reported that mounting and unmounting a specific pattern of corrupted nilfs2 filesystem images causes a use-after-free of metadata file inodes, which triggers a kernel bug in lru_add_fn().
As Jan Kara pointed out, this is because the link count of a metadata file gets corrupted to 0, and nilfs_evict_inode(), which is called from iput(), tries to delete that inode (ifile inode in this case).
The inconsistency occurs because directories containing the inode numbers of these metadata files that should not be visible in the namespace are read without checking.
Fix this issue by treating the inode numbers of these internal files as errors in the sanity check helper when reading directory folios/pages.

lib: objagg: Fix general protection fault
The library supports aggregation of objects into other objects only if the parent object does not have a parent itself. That is, nesting is not supported.
Aggregation happens in two cases: Without and with hints, where hints are a pre-computed recommendation on how to aggregate the provided objects.
Nesting is not possible in the first case due to a check that prevents it, but in the second case there is no check because the assumption is that nesting cannot happen when creating objects based on hints. The violation of this assumption leads to various warnings and eventually to a general protection fault [1].
Before fixing the root cause, error out when nesting happens and warn.

drm/vmwgfx: Fix a deadlock in dma buf fence polling
Introduce a version of the fence ops that on release doesn't remove the fence from the pending list, and thus doesn't require a lock to fix poll->fence wait->fence unref deadlocks.
vmwgfx overwrites the wait callback to iterate over the list of all fences and update their status, to do that it holds a lock to prevent the list modifcations from other threads. The fence destroy callback both deletes the fence and removes it from the list of pending fences, for which it holds a lock.
dma buf polling cb unrefs a fence after it's been signaled: so the poll calls the wait, which signals the fences, which are being destroyed. The destruction tries to acquire the lock on the pending fences list which it can never get because it's held by the wait from which it was called.
Old bug, but not a lot of userspace apps were using dma-buf polling interfaces. Fix those, in particular this fixes KDE stalls/deadlock.(CVE-2024-43863)

x86/mm: Fix pti_clone_pgtable() alignment assumption
Guenter reported dodgy crashes on an i386-nosmp build using GCC-11 that had the form of endless traps until entry stack exhaust and then
DF from the stack guard.
It turned out that pti_clone_pgtable() had alignment assumptions on the start address, notably it hard assumes start is PMD aligned. This is true on x86_64, but very much not true on i386.
These assumptions can cause the end condition to malfunction, leading to a 'short' clone. Guess what happens when the user mapping has a short copy of the entry text?
Use the correct increment form for addr to avoid alignment assumptions.(CVE-2024-44965)

In the Linux kernel, the following vulnerability has been resolved:
vfs: Don't evict inode under the inode lru traversing context
The inode reclaiming process(See function prune_icache_sb) collects all reclaimable inodes and mark them with I_FREEING flag at first, at that time, other processes will be stuck if they try getting these inodes (See function find_inode_fast), then the reclaiming process destroy the inodes by function dispose_list(). Some filesystems(eg. ext4 with ea_inode feature, ubifs with xattr) may do inode lookup in the inode evicting callback function, if the inode lookup is operated under the inode lru traversing context, deadlock problems may happen.
Case 1: In function ext4_evict_inode(), the ea inode lookup could happen if ea_inode feature is enabled, the lookup process will be stuck under the evicting context like this:
- File A has inode i_reg and an ea inode i_ea
- getfattr(A, xattr_buf) // i_ea is added into lru // lru->i_ea
-
Then, following three processes running like this:
PA PB echo 2 > /proc/sys/vm/drop_caches shrink_slab prune_dcache_sb // i_reg is added into lru, lru->i_ea->i_reg prune_icache_sb list_lru_walk_one inode_lru_isolate i_ea->i_state |= I_FREEING // set inode state inode_lru_isolate __iget(i_reg) spin_unlock(&i_reg->i_lock) spin_unlock(lru_lock) rm file A i_reg->nlink = 0 iput(i_reg) // i_reg->nlink is 0, do evict ext4_evict_inode ext4_xattr_delete_inode ext4_xattr_inode_dec_ref_all ext4_xattr_inode_iget ext4_iget(i_ea->i_ino) iget_locked find_inode_fast __wait_on_freeing_inode(i_ea) ----→ AA deadlock dispose_list // cannot be executed by prune_icache_sb wake_up_bit(&i_ea->i_state)
Case 2: In deleted inode writing function ubifs_jnl_write_inode(), file deleting process holds BASEHD's wbuf->io_mutex while getting the xattr inode, which could race with inode reclaiming process(The reclaiming process could try locking BASEHD's wbuf->io_mutex in inode evicting function), then an ABBA deadlock problem would happen as following:
- File A has inode ia and a xattr(with inode ixa), regular file B has inode ib and a xattr.
- getfattr(A, xattr_buf) // ixa is added into lru // lru->ixa
- Then, following three processes running like this:
PA PB PC echo 2 > /proc/sys/vm/drop_caches shrink_slab prune_dcache_sb // ib and ia are added into lru, lru->ixa->ib->ia prune_icache_sb list_lru_walk_one inode_lru_isolate ixa->i_state |= I_FREEING // set inode state inode_lru_isolate __iget(ib) spin_unlock(&ib->i_lock) spin_unlock(lru_lock) rm file B ib->nlink = 0rm file A iput(ia) ubifs_evict_inode(ia) ubifs_jnl_delete_inode(ia) ubifs_jnl_write_inode(ia) make_reservation(BASEHD) // Lock wbuf->io_mutex ubifs_iget(ixa->i_ino) iget_locked find_inode_fast __wait_on_freeing_inode(ixa) | iput(ib) // ib->nlink is 0, do evict | ubifs_evict_inode | ubifs_jnl_delete_inode(ib) ↓ ubifs_jnl_write_inode ABBA deadlock ←-----make_reservation(BASEHD) dispose_list // cannot be executed by prune_icache_sb wake_up_bit(&ixa->i_state)

In the Linux kernel, the following vulnerability has been resolved:
fix bitmap corruption on close_range() with CLOSE_RANGE_UNSHARE
copy_fd_bitmaps(new, old, count) is expected to copy the first count/BITS_PER_LONG bits from old->full_fds_bits[] and fill the rest with zeroes. What it does is copying enough words (BITS_TO_LONGS(count/BITS_PER_LONG)), then memsets the rest. That works fine, if all bits past the cutoff point are clear. Otherwise we are risking garbage from the last word we'd copied.
For most of the callers that is true - expand_fdtable() has count equal to old->max_fds, so there's no open descriptors past count, let alone fully occupied words in ->open_fds[], which is what bits in ->full_fds_bits[] correspond to.
The other caller (dup_fd()) passes sane_fdtable_size(old_fdt, max_fds), which is the smallest multiple of BITS_PER_LONG that covers all opened descriptors below max_fds. In the common case (copying on fork()) max_fds is ~0U, so all opened descriptors will be below it and we are fine, by the same reasons why the call in expand_fdtable() is safe.
Unfortunately, there is a case where max_fds is less than that and where we might, indeed, end up with junk in ->full_fds_bits[] - close_range(from, to, CLOSE_RANGE_UNSHARE) with * descriptor table being currently shared * 'to' being above the current capacity of descriptor table * 'from' being just under some chunk of opened descriptors. In that case we end up with observably wrong behaviour - e.g. spawn a child with CLONE_FILES, get all descriptors in range 0..127 open, then close_range(64, ~0U, CLOSE_RANGE_UNSHARE) and watch dup(0) ending up with descriptor #128, despite #64 being observably not open.
The minimally invasive fix would be to deal with that in dup_fd(). If this proves to add measurable overhead, we can go that way, but let's try to fix copy_fd_bitmaps() first.
- new helper: bitmap_copy_and_expand(to, from, bits_to_copy, size).
- make copy_fd_bitmaps() take the bitmap size in words, rather than bits; it's 'count' argument is always a multiple of BITS_PER_LONG, so we are not losing any information, and that way we can use the same helper for all three bitmaps - compiler will see that count is a multiple of BITS_PER_LONG for the large ones, so it'll generate plain memcpy()+memset().

btrfs: fix qgroup reserve leaks in cow_file_range
In the buffered write path, the dirty page owns the qgroup reserve until it creates an ordered_extent.
Therefore, any errors that occur before the ordered_extent is created must free that reservation, or else the space is leaked. The fstest generic/475 exercises various IO error paths, and is able to trigger errors in cow_file_range where we fail to get to allocating the ordered extent. Note that because we do clear delalloc, we are likely to remove the inode from the delalloc list, so the inodes/pages to not have invalidate/launder called on them in the commit abort path.
This results in failures at the unmount stage of the test that look like:

Squashfs: sanity check symbolic link size
Syzkiller reports a "KMSAN: uninit-value in pick_link" bug.
This is caused by an uninitialised page, which is ultimately caused by a corrupted symbolic link size read from disk.
The reason why the corrupted symlink size causes an uninitialised page is due to the following sequence of events:
-
squashfs_read_inode() is called to read the symbolic link from disk. This assigns the corrupted value 3875536935 to inode->i_size.
-
Later squashfs_symlink_read_folio() is called, which assigns this corrupted value to the length variable, which being a signed int, overflows producing a negative number.
-
The following loop that fills in the page contents checks that the copied bytes is less than length, which being negative means the loop is skipped, producing an uninitialised page.
This patch adds a sanity check which checks that the symbolic link size is not larger than expected.

userfaultfd: fix checks for huge PMDs
Patch series "userfaultfd: fix races around pmd_trans_huge() check", v2.
The pmd_trans_huge() code in mfill_atomic() is wrong in three different ways depending on kernel version:
- The pmd_trans_huge() check is racy and can lead to a BUG_ON() (if you hit the right two race windows) - I've tested this in a kernel build with some extra mdelay() calls. See the commit message for a description of the race scenario. On older kernels (before 6.5), I think the same bug can even theoretically lead to accessing transhuge page contents as a page table if you hit the right 5 narrow race windows (I haven't tested this case).
- As pointed out by Qi Zheng, pmd_trans_huge() is not sufficient for detecting PMDs that don't point to page tables. On older kernels (before 6.5), you'd just have to win a single fairly wide race to hit this. I've tested this on 6.1 stable by racing migration (with a mdelay() patched into try_to_migrate()) against UFFDIO_ZEROPAGE - on my x86 VM, that causes a kernel oops in ptlock_ptr().
- On newer kernels (>=6.5), for shmem mappings, khugepaged is allowed to yank page tables out from under us (though I haven't tested that), so I think the BUG_ON() checks in mfill_atomic() are just wrong.
I decided to write two separate fixes for these (one fix for bugs 1+2, one fix for bug 3), so that the first fix can be backported to kernels affected by bugs 1+2.
This patch (of 2):
This fixes two issues.
I discovered that the following race can occur:

I have experimentally verified this in a kernel with extra mdelay() calls; the BUG_ON(pmd_none(*dst_pmd)) triggers.
On kernels newer than commit 0d940a9b270b ("mm/pgtable: allow pte_offset_map_lock to fail"), this can't lead to anything worse than a BUG_ON(), since the page table access helpers are actually designed to deal with page tables concurrently disappearing; but on older kernels (<=6.4), I think we could probably theoretically race past the two BUG_ON() checks and end up treating a hugepage as a page table.
The second issue is that, as Qi Zheng pointed out, there are other types of huge PMDs that pmd_trans_huge() can't catch: devmap PMDs and swap PMDs (in particular, migration PMDs).
On <=6.4, this is worse than the first issue: If mfill_atomic() runs on a PMD that contains a migration entry (which just requires winning a single, fairly wide race), it will pass the PMD to pte_offset_map_lock(), which assumes that the PMD points to a page table.
Breakage follows: First, the kernel tries to take the PTE lock (which will crash or maybe worse if there is no "struct page" for the address bits in the migration entry PMD - I think at least on X86 there usually is no corresponding "struct page" thanks to the PTE inversion mitigation, amd64 looks different).
If that didn't crash, the kernel would next try to write a PTE into what it wrongly thinks is a page table.
As part of fixing these issues, get rid of the check for pmd_trans_huge() before __pte_alloc() - that's redundant, we're going to have to check for that after the __pte_alloc() anyway.
Backport note: pmdp_get_lockless() is pmd_read_atomic() in older kernels.(CVE-2024-46787)
In the Linux kernel, the following vulnerability has been resolved:
sch/netem: fix use after free in netem_dequeue
If netem_dequeue() enqueues packet to inner qdisc and that qdisc returns __NET_XMIT_STOLEN. The packet is dropped but qdisc_tree_reduce_backlog() is not called to update the parent's q.qlen, leading to the similar use-after-free as Commit e04991a48dbaf382 ("netem: fix return value if duplicate enqueue fails")

What it does is copying enough words\n(BITS_TO_LONGS(count/BITS_PER_LONG)), then memsets the rest.\nThat works fine, *if* all bits past the cutoff point are\nclear. Otherwise we are risking garbage from the last word\nwe\u0026apos;d copied.\r\n\r\nFor most of the callers that is true - expand_fdtable() has\ncount equal to old-\u0026gt;max_fds, so there\u0026apos;s no open descriptors\npast count, let alone fully occupied words in -\u0026gt;open_fds[],\nwhich is what bits in -\u0026gt;full_fds_bits[] correspond to.\r\n\r\nThe other caller (dup_fd()) passes sane_fdtable_size(old_fdt, max_fds),\nwhich is the smallest multiple of BITS_PER_LONG that covers all\nopened descriptors below max_fds. In the common case (copying on\nfork()) max_fds is ~0U, so all opened descriptors will be below\nit and we are fine, by the same reasons why the call in expand_fdtable()\nis safe.\r\n\r\nUnfortunately, there is a case where max_fds is less than that\nand where we might, indeed, end up with junk in -\u0026gt;full_fds_bits[] -\nclose_range(from, to, CLOSE_RANGE_UNSHARE) with\n\t* descriptor table being currently shared\n\t* \u0026apos;to\u0026apos; being above the current capacity of descriptor table\n\t* \u0026apos;from\u0026apos; being just under some chunk of opened descriptors.\nIn that case we end up with observably wrong behaviour - e.g. spawn\na child with CLONE_FILES, get all descriptors in range 0..127 open,\nthen close_range(64, ~0U, CLOSE_RANGE_UNSHARE) and watch dup(0) ending\nup with descriptor #128, despite #64 being observably not open.\r\n\r\nThe minimally invasive fix would be to deal with that in dup_fd().\nIf this proves to add measurable overhead, we can go that way, but\nlet\u0026apos;s try to fix copy_fd_bitmaps() first.\r\n\r\n* new helper: bitmap_copy_and_expand(to, from, bits_to_copy, size).\n* make copy_fd_bitmaps() take the bitmap size in words, rather than\nbits; it\u0026apos;s \u0026apos;count\u0026apos; argument is always a multiple of BITS_PER_LONG,\nso we are not losing any information, and that way we can use the\nsame helper for all three bitmaps - compiler will see that count\nis a multiple of BITS_PER_LONG for the large ones, so it\u0026apos;ll generate\nplain memcpy()+memset().\r\n\r\nReproducer added to tools/testing/selftests/core/close_range_test.c(CVE-2024-45025)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nmmc: mmc_test: Fix NULL dereference on allocation failure\r\n\r\nIf the \u0026quot;test-\u0026gt;highmem = alloc_pages()\u0026quot; allocation fails then calling\n__free_pages(test-\u0026gt;highmem) will result in a NULL dereference. Also\nchange the error code to -ENOMEM instead of returning success.(CVE-2024-45028)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\ndrm/amd/display: Skip wbscl_set_scaler_filter if filter is null\r\n\r\nCallers can pass null in filter (i.e. from returned from the function\nwbscl_get_filter_coeffs_16p) and a null check is added to ensure that is\nnot the case.\r\n\r\nThis fixes 4 NULL_RETURNS issues reported by Coverity.(CVE-2024-46714)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\ndrm/amdgpu: fix ucode out-of-bounds read warning\r\n\r\nClear warning that read ucode[] may out-of-bounds.(CVE-2024-46723)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\ndrm/amd/pm: fix the Out-of-bounds read warning\r\n\r\nusing index i - 1U may beyond element index\nfor mc_data[] when i = 0.(CVE-2024-46731)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nbtrfs: fix qgroup reserve leaks in cow_file_range\r\n\r\nIn the buffered write path, the dirty page owns the qgroup reserve until\nit creates an ordered_extent.\r\n\r\nTherefore, any errors that occur before the ordered_extent is created\nmust free that reservation, or else the space is leaked. The fstest\ngeneric/475 exercises various IO error paths, and is able to trigger\nerrors in cow_file_range where we fail to get to allocating the ordered\nextent. Note that because we *do* clear delalloc, we are likely to\nremove the inode from the delalloc list, so the inodes/pages to not have\ninvalidate/launder called on them in the commit abort path.\r\n\r\nThis results in failures at the unmount stage of the test that look like:\r\n\r\n BTRFS: error (device dm-8 state EA) in cleanup_transaction:2018: errno=-5 IO failure\n BTRFS: error (device dm-8 state EA) in btrfs_replace_file_extents:2416: errno=-5 IO failure\n BTRFS warning (device dm-8 state EA): qgroup 0/5 has unreleased space, type 0 rsv 28672\n ------------[ cut here ]------------\n WARNING: CPU: 3 PID: 22588 at fs/btrfs/disk-io.c:4333 close_ctree+0x222/0x4d0 [btrfs]\n Modules linked in: btrfs blake2b_generic libcrc32c xor zstd_compress raid6_pq\n CPU: 3 PID: 22588 Comm: umount Kdump: loaded Tainted: G W 6.10.0-rc7-gab56fde445b8 #21\n Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS Arch Linux 1.16.3-1-1 04/01/2014\n RIP: 0010:close_ctree+0x222/0x4d0 [btrfs]\n RSP: 0018:ffffb4465283be00 EFLAGS: 00010202\n RAX: 0000000000000001 RBX: ffffa1a1818e1000 RCX: 0000000000000001\n RDX: 0000000000000000 RSI: ffffb4465283bbe0 RDI: ffffa1a19374fcb8\n RBP: ffffa1a1818e13c0 R08: 0000000100028b16 R09: 0000000000000000\n R10: 0000000000000003 R11: 0000000000000003 R12: ffffa1a18ad7972c\n R13: 0000000000000000 R14: 0000000000000000 R15: 0000000000000000\n FS: 00007f9168312b80(0000) GS:ffffa1a4afcc0000(0000) knlGS:0000000000000000\n CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n CR2: 00007f91683c9140 CR3: 000000010acaa000 CR4: 00000000000006f0\n Call Trace:\n \u0026lt;TASK\u0026gt;\n ? close_ctree+0x222/0x4d0 [btrfs]\n ? __warn.cold+0x8e/0xea\n ? close_ctree+0x222/0x4d0 [btrfs]\n ? report_bug+0xff/0x140\n ? handle_bug+0x3b/0x70\n ? exc_invalid_op+0x17/0x70\n ? asm_exc_invalid_op+0x1a/0x20\n ? close_ctree+0x222/0x4d0 [btrfs]\n generic_shutdown_super+0x70/0x160\n kill_anon_super+0x11/0x40\n btrfs_kill_super+0x11/0x20 [btrfs]\n deactivate_locked_super+0x2e/0xa0\n cleanup_mnt+0xb5/0x150\n task_work_run+0x57/0x80\n syscall_exit_to_user_mode+0x121/0x130\n do_syscall_64+0xab/0x1a0\n entry_SYSCALL_64_after_hwframe+0x77/0x7f\n RIP: 0033:0x7f916847a887\n ---[ end trace 0000000000000000 ]---\n BTRFS error (device dm-8 state EA): qgroup reserved space leaked\r\n\r\nCases 2 and 3 in the out_reserve path both pertain to this type of leak\nand must free the reserved qgroup data.

This assigns the corrupted value\n 3875536935 to inode-\u0026gt;i_size.\r\n\r\n2. Later squashfs_symlink_read_folio() is called, which assigns\n this corrupted value to the length variable, which being a\n signed int, overflows producing a negative number.\r\n\r\n3. The following loop that fills in the page contents checks that\n the copied bytes is less than length, which being negative means\n the loop is skipped, producing an uninitialised page.\r\n\r\nThis patch adds a sanity check which checks that the symbolic\nlink size is not larger than expected.\r\n\r\n--\r\n\r\nV2: fix spelling mistake.(CVE-2024-46744)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nInput: uinput - reject requests with unreasonable number of slots\r\n\r\n\nWhen exercising uinput interface syzkaller may try setting up device\nwith a really large number of slots, which causes memory allocation\nfailure in input_mt_init_slots(). While this allocation failure is\nhandled properly and request is rejected, it results in syzkaller\nreports. Additionally, such request may put undue burden on the\nsystem which will try to free a lot of memory for a bogus request.\r\n\r\nFix it by limiting allowed number of slots to 100. This can easily\nbe extended if we see devices that can track more than 100 contacts.(CVE-2024-46745)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nHID: cougar: fix slab-out-of-bounds Read in cougar_report_fixup\r\n\r\nreport_fixup for the Cougar 500k Gaming Keyboard was not verifying\nthat the report descriptor size was correct before accessing it(CVE-2024-46747)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nbtrfs: don\u0026apos;t BUG_ON() when 0 reference count at btrfs_lookup_extent_info()\r\n\r\nInstead of doing a BUG_ON() handle the error by returning -EUCLEAN,\naborting the transaction and logging an error message.(CVE-2024-46751)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nbtrfs: replace BUG_ON() with error handling at update_ref_for_cow()\r\n\r\nInstead of a BUG_ON() just return an error, log an error message and\nabort the transaction in case we find an extent buffer belonging to the\nrelocation tree that doesn\u0026apos;t have the full backref flag set. This is\nunexpected and should never happen (save for bugs or a potential bad\nmemory).(CVE-2024-46752)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nuserfaultfd: fix checks for huge PMDs\r\n\r\nPatch series \u0026quot;userfaultfd: fix races around pmd_trans_huge() check\u0026quot;, v2.\r\n\r\nThe pmd_trans_huge() code in mfill_atomic() is wrong in three different\nways depending on kernel version:\r\n\r\n1. The pmd_trans_huge() check is racy and can lead to a BUG_ON() (if you hit\n the right two race windows) - I\u0026apos;ve tested this in a kernel build with\n some extra mdelay() calls. See the commit message for a description\n of the race scenario.\n On older kernels (before 6.5), I think the same bug can even\n theoretically lead to accessing transhuge page contents as a page table\n if you hit the right 5 narrow race windows (I haven\u0026apos;t tested this case).\n2. As pointed out by Qi Zheng, pmd_trans_huge() is not sufficient for\n detecting PMDs that don\u0026apos;t point to page tables.\n On older kernels (before 6.5), you\u0026apos;d just have to win a single fairly\n wide race to hit this.\n I\u0026apos;ve tested this on 6.1 stable by racing migration (with a mdelay()\n patched into try_to_migrate()) against UFFDIO_ZEROPAGE - on my x86\n VM, that causes a kernel oops in ptlock_ptr().\n3. On newer kernels (\u0026gt;=6.5), for shmem mappings, khugepaged is allowed\n to yank page tables out from under us (though I haven\u0026apos;t tested that),\n so I think the BUG_ON() checks in mfill_atomic() are just wrong.\r\n\r\nI decided to write two separate fixes for these (one fix for bugs 1+2, one\nfix for bug 3), so that the first fix can be backported to kernels\naffected by bugs 1+2.\r\n\r\n\nThis patch (of 2):\r\n\r\nThis fixes two issues.\r\n\r\nI discovered that the following race can occur:\r\n\r\n mfill_atomic other thread\n ============ ============\n \u0026lt;zap PMD\u0026gt;\n pmdp_get_lockless() [reads none pmd]\n \u0026lt;bail if trans_huge\u0026gt;\n \u0026lt;if none:\u0026gt;\n \u0026lt;pagefault creates transhuge zeropage\u0026gt;\n __pte_alloc [no-op]\n \u0026lt;zap PMD\u0026gt;\n \u0026lt;bail if pmd_trans_huge(*dst_pmd)\u0026gt;\n BUG_ON(pmd_none(*dst_pmd))\r\n\r\nI have experimentally verified this in a kernel with extra mdelay() calls;\nthe BUG_ON(pmd_none(*dst_pmd)) triggers.\r\n\r\nOn kernels newer than commit 0d940a9b270b (\u0026quot;mm/pgtable: allow\npte_offset_map[_lock]() to fail\u0026quot;), this can\u0026apos;t lead to anything worse than\na BUG_ON(), since the page table access helpers are actually designed to\ndeal with page tables concurrently disappearing; but on older kernels\n(\u0026lt;=6.4), I think we could probably theoretically race past the two\nBUG_ON() checks and end up treating a hugepage as a page table.\r\n\r\nThe second issue is that, as Qi Zheng pointed out, there are other types\nof huge PMDs that pmd_trans_huge() can\u0026apos;t catch: devmap PMDs and swap PMDs\n(in particular, migration PMDs).\r\n\r\nOn \u0026lt;=6.4, this is worse than the first issue: If mfill_atomic() runs on a\nPMD that contains a migration entry (which just requires winning a single,\nfairly wide race), it will pass the PMD to pte_offset_map_lock(), which\nassumes that the PMD points to a page table.\r\n\r\nBreakage follows: First, the kernel tries to take the PTE lock (which will\ncrash or maybe worse if there is no \u0026quot;struct page\u0026quot; for the address bits in\nthe migration entry PMD - I think at least on X86 there usually is no\ncorresponding \u0026quot;struct page\u0026quot; thanks to the PTE inversion mitigation, amd64\nlooks different).\r\n\r\nIf that didn\u0026apos;t crash, the kernel would next try to write a PTE into what\nit wrongly thinks is a page table.\r\n\r\nAs part of fixing these issues, get rid of the check for pmd_trans_huge()\nbefore __pte_alloc() - that\u0026apos;s redundant, we\u0026apos;re going to have to check for\nthat after the __pte_alloc() anyway.\r\n\r\nBackport note: pmdp_get_lockless() is pmd_read_atomic() in older kernels.(CVE-2024-46787)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nsch/netem: fix use after free in netem_dequeue\r\n\r\nIf netem_dequeue() enqueues packet to inner qdisc and that qdisc\nreturns __NET_XMIT_STOLEN.

Vulnerability from osv_openeuler – Published: 2024-09-27 11:07 – Updated: 2026-08-06 11:07 – Source websiteThe Linux Kernel, the operating system core itself.
Security Fix(es):
In the Linux kernel, the following vulnerability has been resolved:
NFSD: Fix ia_size underflow
iattr::ia_size is a loff_t, which is a signed 64-bit type. NFSv3 and NFSv4 both define file size as an unsigned 64-bit type. Thus there is a range of valid file size values an NFS client can send that is already larger than Linux can handle.
Currently decode_fattr4() dumps a full u64 value into ia_size. If that value happens to be larger than S64_MAX, then ia_size underflows. I'm about to fix up the NFSv3 behavior as well, so let's catch the underflow in the common code path: nfsd_setattr().(CVE-2022-48828)

misc: fastrpc: Fix use-after-free race condition for maps
It is possible that in between calling fastrpc_map_get() until map->fl->lock is taken in fastrpc_free_map(), another thread can call fastrpc_map_lookup() and get a reference to a map that is about to be deleted.
Rewrite fastrpc_map_get() to only increase the reference count of a map if it's non-zero. Propagate this to callers so they can know if a map is about to be deleted.

drm/amd/pm: fix a double-free in si_dpm_init
When the allocation of adev->pm.dpm.dyn_state.vddc_dependency_on_dispclk.entries fails, amdgpu_free_extended_power_table is called to free some fields of adev. However, when the control flow returns to si_dpm_sw_init, it goes to label dpm_failed and calls si_dpm_fini, which calls amdgpu_free_extended_power_table again and free those fields again. Thus a double-free is triggered.(CVE-2023-52691)
In the Linux kernel, the following vulnerability has been resolved:
f2fs: avoid format-overflow warning
With gcc and W=1 option, there's a warning like this:

usb: gadget: f_ncm: fix potential NULL ptr deref in ncm_bitrate()
In Google internal bug 265639009 we've received an (as yet) unreproducible crash report from an aarch64 GKI 5.10.149-android13 running device.
AFAICT the source code is at: https://android.googlesource.com/kernel/common/+/refs/tags/ASB-2022-12-05_13-5.10
The call stack is: ncm_close() -> ncm_notify() -> ncm_do_notify() with the crash at: ncm_do_notify+0x98/0x270 Code: 79000d0b b9000a6c f940012a f9400269 (b9405d4b)
Which I believe disassembles to (I don't know ARM assembly, but it looks sane enough to me...):
// halfword (16-bit) store presumably to event->wLength (at offset 6 of struct usb_cdc_notification) 0B 0D 00 79 strh w11, [x8, #6]
// word (32-bit) store presumably to req->Length (at offset 8 of struct usb_request) 6C 0A 00 B9 str w12, [x19, #8]
// x10 (NULL) was read here from offset 0 of valid pointer x9 // IMHO we're reading 'cdev->gadget' and getting NULL // gadget is indeed at offset 0 of struct usb_composite_dev 2A 01 40 F9 ldr x10, [x9]
// loading req->buf pointer, which is at offset 0 of struct usb_request 69 02 40 F9 ldr x9, [x19]
// x10 is null, crash, appears to be attempt to read cdev->gadget->max_speed 4B 5D 40 B9 ldr w11, [x10, #0x5c]
which seems to line up with ncm_do_notify() case NCM_NOTIFY_SPEED code fragment:
event->wLength = cpu_to_le16(8); req->length = NCM_STATUS_BYTECOUNT;
/ SPEED_CHANGE data is up/down speeds in bits/sec / data = req->buf + sizeof *event; data[0] = cpu_to_le32(ncm_bitrate(cdev->gadget));
My analysis of registers and NULL ptr deref crash offset (Unable to handle kernel NULL pointer dereference at virtual address 000000000000005c) heavily suggests that the crash is due to 'cdev->gadget' being NULL when executing: data[0] = cpu_to_le32(ncm_bitrate(cdev->gadget)); which calls: ncm_bitrate(NULL) which then calls: gadget_is_superspeed(NULL) which reads ((struct usb_gadget *)NULL)->max_speed and hits a panic.
AFAICT, if I'm counting right, the offset of max_speed is indeed 0x5C. (remember there's a GKI KABI reservation of 16 bytes in struct work_struct)
It's not at all clear to me how this is all supposed to work... but returning 0 seems much better than panic-ing...(CVE-2023-52894)
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix general protection fault in nilfs_btree_insert()
If nilfs2 reads a corrupted disk image and tries to reads a b-tree node block by calling __nilfs_btree_get_block() against an invalid virtual block address, it returns -ENOENT because conversion of the virtual block address to a disk block address fails. However, this return value is the same as the internal code that b-tree lookup routines return to indicate that the block being searched does not exist, so functions that operate on that b-tree may misbehave.
When nilfs_btree_insert() receives this spurious 'not found' code from nilfs_btree_do_lookup(), it misunderstands that the 'not found' check was successful and continues the insert operation using incomplete lookup path data, causing the following crash:

This patch fixes the root cause of this problem by replacing the error code that __nilfs_btree_get_block() returns on block address conversion failure from -ENOENT to another internal code -EINVAL which means that the b-tree metadata is corrupted.
By returning -EINVAL, it propagates without glitches, and for all relevant b-tree operations, functions in the upper bmap layer output an error message indicating corrupted b-tree metadata via nilfs_bmap_convert_error(), and code -EIO will be eventually returned as it should be.(CVE-2023-52900)

nilfs2: add missing check for inode numbers on directory entries
Syzbot reported that mounting and unmounting a specific pattern of corrupted nilfs2 filesystem images causes a use-after-free of metadata file inodes, which triggers a kernel bug in lru_add_fn().
As Jan Kara pointed out, this is because the link count of a metadata file gets corrupted to 0, and nilfs_evict_inode(), which is called from iput(), tries to delete that inode (ifile inode in this case).
The inconsistency occurs because directories containing the inode numbers of these metadata files that should not be visible in the namespace are read without checking.
Fix this issue by treating the inode numbers of these internal files as errors in the sanity check helper when reading directory folios/pages.

x86/mm: Fix pti_clone_pgtable() alignment assumption
Guenter reported dodgy crashes on an i386-nosmp build using GCC-11 that had the form of endless traps until entry stack exhaust and then
DF from the stack guard.
It turned out that pti_clone_pgtable() had alignment assumptions on the start address, notably it hard assumes start is PMD aligned. This is true on x86_64, but very much not true on i386.
These assumptions can cause the end condition to malfunction, leading to a 'short' clone. Guess what happens when the user mapping has a short copy of the entry text?

select_local_address() and select_signal_address() both select an endpoint entry from the list inside an RCU protected section, but return a reference to it, to be read later on. If the entry is dereferenced after the RCU unlock, reading info could cause a Use-after-Free.
A simple solution is to copy the required info while inside the RCU protected section to avoid any risk of UaF later. The address ID might need to be modified later to handle the ID0 case later, so a copy seems OK to deal with.(CVE-2024-44974)
In the Linux kernel, the following vulnerability has been resolved:
net: hns3: fix a deadlock problem when config TC during resetting
When config TC during the reset process, may cause a deadlock, the flow is as below: pf reset start │ ▼ ...... setup tc │ │ ▼ ▼ DOWN: napi_disable() napi_disable()(skip) │ │ │ ▼ ▼ ...... ...... │ │ ▼ │ napi_enable() │ ▼ UINIT: netif_napi_del() │ ▼ ...... │ ▼ INIT: netif_napi_add() │ ▼ ...... global reset start │ │ ▼ ▼ UP: napi_enable()(skip) ...... │ │ ▼ ▼ ...... napi_disable()
In reset process, the driver will DOWN the port and then UINIT, in this case, the setup tc process will UP the port before UINIT, so cause the problem. Adds a DOWN process in UINIT to fix it.(CVE-2024-44995)

In the Linux kernel, the following vulnerability has been resolved:
vfs: Don't evict inode under the inode lru traversing context
The inode reclaiming process(See function prune_icache_sb) collects all reclaimable inodes and mark them with I_FREEING flag at first, at that time, other processes will be stuck if they try getting these inodes (See function find_inode_fast), then the reclaiming process destroy the inodes by function dispose_list(). Some filesystems(eg. ext4 with ea_inode feature, ubifs with xattr) may do inode lookup in the inode evicting callback function, if the inode lookup is operated under the inode lru traversing context, deadlock problems may happen.
Case 1: In function ext4_evict_inode(), the ea inode lookup could happen if ea_inode feature is enabled, the lookup process will be stuck under the evicting context like this:
- File A has inode i_reg and an ea inode i_ea
- getfattr(A, xattr_buf) // i_ea is added into lru // lru->i_ea
-
Then, following three processes running like this:
PA PB echo 2 > /proc/sys/vm/drop_caches shrink_slab prune_dcache_sb // i_reg is added into lru, lru->i_ea->i_reg prune_icache_sb list_lru_walk_one inode_lru_isolate i_ea->i_state |= I_FREEING // set inode state inode_lru_isolate __iget(i_reg) spin_unlock(&i_reg->i_lock) spin_unlock(lru_lock) rm file A i_reg->nlink = 0 iput(i_reg) // i_reg->nlink is 0, do evict ext4_evict_inode ext4_xattr_delete_inode ext4_xattr_inode_dec_ref_all ext4_xattr_inode_iget ext4_iget(i_ea->i_ino) iget_locked find_inode_fast __wait_on_freeing_inode(i_ea) ----→ AA deadlock dispose_list // cannot be executed by prune_icache_sb wake_up_bit(&i_ea->i_state)
Case 2: In deleted inode writing function ubifs_jnl_write_inode(), file deleting process holds BASEHD's wbuf->io_mutex while getting the xattr inode, which could race with inode reclaiming process(The reclaiming process could try locking BASEHD's wbuf->io_mutex in inode evicting function), then an ABBA deadlock problem would happen as following:
- File A has inode ia and a xattr(with inode ixa), regular file B has inode ib and a xattr.
- getfattr(A, xattr_buf) // ixa is added into lru // lru->ixa
- Then, following three processes running like this:
PA PB PC echo 2 > /proc/sys/vm/drop_caches shrink_slab prune_dcache_sb // ib and ia are added into lru, lru->ixa->ib->ia prune_icache_sb list_lru_walk_one inode_lru_isolate ixa->i_state |= I_FREEING // set inode state inode_lru_isolate __iget(ib) spin_unlock(&ib->i_lock) spin_unlock(lru_lock) rm file B ib->nlink = 0rm file A iput(ia) ubifs_evict_inode(ia) ubifs_jnl_delete_inode(ia) ubifs_jnl_write_inode(ia) make_reservation(BASEHD) // Lock wbuf->io_mutex ubifs_iget(ixa->i_ino) iget_locked find_inode_fast __wait_on_freeing_inode(ixa) | iput(ib) // ib->nlink is 0, do evict | ubifs_evict_inode | ubifs_jnl_delete_inode(ib) ↓ ubifs_jnl_write_inode ABBA deadlock ←-----make_reservation(BASEHD) dispose_list // cannot be executed by prune_icache_sb wake_up_bit(&ixa->i_state)

In the Linux kernel, the following vulnerability has been resolved:
mmc: mmc_test: Fix NULL dereference on allocation failure

In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix qgroup reserve leaks in cow_file_range
In the buffered write path, the dirty page owns the qgroup reserve until it creates an ordered_extent.
Therefore, any errors that occur before the ordered_extent is created must free that reservation, or else the space is leaked. The fstest generic/475 exercises various IO error paths, and is able to trigger errors in cow_file_range where we fail to get to allocating the ordered extent. Note that because we do clear delalloc, we are likely to remove the inode from the delalloc list, so the inodes/pages to not have invalidate/launder called on them in the commit abort path.
This results in failures at the unmount stage of the test that look like:

In the Linux kernel, the following vulnerability has been resolved:
Squashfs: sanity check symbolic link size
Syzkiller reports a "KMSAN: uninit-value in pick_link" bug.
This is caused by an uninitialised page, which is ultimately caused by a corrupted symbolic link size read from disk.
The reason why the corrupted symlink size causes an uninitialised page is due to the following sequence of events:
-
squashfs_read_inode() is called to read the symbolic link from disk. This assigns the corrupted value 3875536935 to inode->i_size.
-
Later squashfs_symlink_read_folio() is called, which assigns this corrupted value to the length variable, which being a signed int, overflows producing a negative number.
-
The following loop that fills in the page contents checks that the copied bytes is less than length, which being negative means the loop is skipped, producing an uninitialised page.
This patch adds a sanity check which checks that the symbolic link size is not larger than expected.

V2: fix spelling mistake.(CVE-2024-46744)
In the Linux kernel, the following vulnerability has been resolved:
Input: uinput - reject requests with unreasonable number of slots
When exercising uinput interface syzkaller may try setting up device with a really large number of slots, which causes memory allocation failure in input_mt_init_slots(). While this allocation failure is handled properly and request is rejected, it results in syzkaller reports. Additionally, such request may put undue burden on the system which will try to free a lot of memory for a bogus request.
Fix it by limiting allowed number of slots to 100. This can easily be extended if we see devices that can track more than 100 contacts.(CVE-2024-46745)

Instead of a BUG_ON() just return an error, log an error message and abort the transaction in case we find an extent buffer belonging to the relocation tree that doesn't have the full backref flag set. This is unexpected and should never happen (save for bugs or a potential bad memory).(CVE-2024-46752)
In the Linux kernel, the following vulnerability has been resolved:
userfaultfd: fix checks for huge PMDs
Patch series "userfaultfd: fix races around pmd_trans_huge() check", v2.
The pmd_trans_huge() code in mfill_atomic() is wrong in three different ways depending on kernel version:
- The pmd_trans_huge() check is racy and can lead to a BUG_ON() (if you hit the right two race windows) - I've tested this in a kernel build with some extra mdelay() calls. See the commit message for a description of the race scenario. On older kernels (before 6.5), I think the same bug can even theoretically lead to accessing transhuge page contents as a page table if you hit the right 5 narrow race windows (I haven't tested this case).
- As pointed out by Qi Zheng, pmd_trans_huge() is not sufficient for detecting PMDs that don't point to page tables. On older kernels (before 6.5), you'd just have to win a single fairly wide race to hit this. I've tested this on 6.1 stable by racing migration (with a mdelay() patched into try_to_migrate()) against UFFDIO_ZEROPAGE - on my x86 VM, that causes a kernel oops in ptlock_ptr().
- On newer kernels (>=6.5), for shmem mappings, khugepaged is allowed to yank page tables out from under us (though I haven't tested that), so I think the BUG_ON() checks in mfill_atomic() are just wrong.
I decided to write two separate fixes for these (one fix for bugs 1+2, one fix for bug 3), so that the first fix can be backported to kernels affected by bugs 1+2.
This patch (of 2):
This fixes two issues.
I discovered that the following race can occur:
mfill_atomic other thread ============ ============ <zap PMD> pmdp_get_lockless() [reads none pmd] <bail if trans_huge> <if none:> <pagefault creates transhuge zeropage> __pte_alloc [no-op] <zap PMD> <bail if pmd_trans_huge(dst_pmd)> BUG_ON(pmd_none(dst_pmd))
I have experimentally verified this in a kernel with extra mdelay() calls; the BUG_ON(pmd_none(*dst_pmd)) triggers.
On kernels newer than commit 0d940a9b270b ("mm/pgtable: allow pte_offset_map_lock to fail"), this can't lead to anything worse than a BUG_ON(), since the page table access helpers are actually designed to deal with page tables concurrently disappearing; but on older kernels (<=6.4), I think we could probably theoretically race past the two BUG_ON() checks and end up treating a hugepage as a page table.
The second issue is that, as Qi Zheng pointed out, there are other types of huge PMDs that pmd_trans_huge() can't catch: devmap PMDs and swap PMDs (in particular, migration PMDs).
On <=6.4, this is worse than the first issue: If mfill_atomic() runs on a PMD that contains a migration entry (which just requires winning a single, fairly wide race), it will pass the PMD to pte_offset_map_lock(), which assumes that the PMD points to a page table.
Breakage follows: First, the kernel tries to take the PTE lock (which will crash or maybe worse if there is no "struct page" for the address bits in the migration entry PMD - I think at least on X86 there usually is no corresponding "struct page" thanks to the PTE inversion mitigation, amd64 looks different).
If that didn't crash, the kernel would next try to write a PTE into what it wrongly thinks is a page table.
As part of fixing these issues, get rid of the check for pmd_trans_huge() before __pte_alloc() - that's redundant, we're going to have to check for that after the __pte_alloc() anyway.
Backport note: pmdp_get_lockless() is pmd_read_atomic() in older kernels.(CVE-2024-46787)

entries\r\n\r\nSyzbot reported that mounting and unmounting a specific pattern of\ncorrupted nilfs2 filesystem images causes a use-after-free of metadata\nfile inodes, which triggers a kernel bug in lru_add_fn().\r\n\r\nAs Jan Kara pointed out, this is because the link count of a metadata file\ngets corrupted to 0, and nilfs_evict_inode(), which is called from iput(),\ntries to delete that inode (ifile inode in this case).\r\n\r\nThe inconsistency occurs because directories containing the inode numbers\nof these metadata files that should not be visible in the namespace are\nread without checking.\r\n\r\nFix this issue by treating the inode numbers of these internal files as\nerrors in the sanity check helper when reading directory folios/pages.\r\n\r\nAlso thanks to Hillf Danton and Matthew Wilcox for their initial mm-layer\nanalysis.(CVE-2024-42104)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\ndrm/amd/display: Skip finding free audio for

This can easily\nbe extended if we see devices that can track more than 100 contacts.(CVE-2024-46745)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nHID: cougar: fix slab-out-of-bounds Read in cougar_report_fixup\r\n\r\nreport_fixup for the Cougar 500k Gaming Keyboard was not verifying\nthat the report descriptor size was correct before accessing it(CVE-2024-46747)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nbtrfs: don\u0026apos;t BUG_ON() when 0 reference count at btrfs_lookup_extent_info()\r\n\r\nInstead of doing a BUG_ON() handle the error by returning -EUCLEAN,\naborting the transaction and logging an error message.(CVE-2024-46751)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nbtrfs: replace BUG_ON() with error handling at update_ref_for_cow()\r\n\r\nInstead of a BUG_ON() just return an error, log an error message and\nabort the transaction in case we find an extent buffer belonging to the\nrelocation tree that doesn\u0026apos;t have the full backref flag set. This is\nunexpected and should never happen (save for bugs or a potential bad\nmemory).(CVE-2024-46752)\r\n\r\nIn the Linux kernel, the following vulnerability has been resolved:\r\n\r\nuserfaultfd: fix checks for huge PMDs\r\n\r\nPatch series \u0026quot;userfaultfd: fix races around pmd_trans_huge() check\u0026quot;, v2.\r\n\r\nThe pmd_trans_huge() code in mfill_atomic() is wrong in three different\nways depending on kernel version:\r\n\r\n1. The pmd_trans_huge() check is racy and can lead to a BUG_ON() (if you hit\n the right two race windows) - I\u0026apos;ve tested this in a kernel build with\n some extra mdelay() calls. See the commit message for a description\n of the race scenario.\n On older kernels (before 6.5), I think the same bug can even\n theoretically lead to accessing transhuge page contents as a page table\n if you hit the right 5 narrow race windows (I haven\u0026apos;t tested this case).\n2. As pointed out by Qi Zheng, pmd_trans_huge() is not sufficient for\n detecting PMDs that don\u0026apos;t point to page tables.\n On older kernels (before 6.5), you\u0026apos;d just have to win a single fairly\n wide race to hit this.\n I\u0026apos;ve tested this on 6.1 stable by racing migration (with a mdelay()\n patched into try_to_migrate()) against UFFDIO_ZEROPAGE - on my x86\n VM, that causes a kernel oops in ptlock_ptr().\n3. On newer kernels (\u0026gt;=6.5), for shmem mappings, khugepaged is allowed\n to yank page tables out from under us (though I haven\u0026apos;t tested that),\n so I think the BUG_ON() checks in mfill_atomic() are just wrong.\r\n\r\nI decided to write two separate fixes for these (one fix for bugs 1+2, one\nfix for bug 3), so that the first fix can be backported to kernels\naffected by bugs 1+2.\r\n\r\n\nThis patch (of 2):\r\n\r\nThis fixes two issues.\r\n\r\nI discovered that the following race can occur:\r\n\r\n mfill_atomic other thread\n ============ ============\n \u0026lt;zap PMD\u0026gt;\n pmdp_get_lockless() [reads none pmd]\n \u0026lt;bail if trans_huge\u0026gt;\n \u0026lt;if none:\u0026gt;\n \u0026lt;pagefault creates transhuge zeropage\u0026gt;\n __pte_alloc [no-op]\n \u0026lt;zap PMD\u0026gt;\n \u0026lt;bail if pmd_trans_huge(*dst_pmd)\u0026gt;\n BUG_ON(pmd_none(*dst_pmd))\r\n\r\nI have experimentally verified this in a kernel with extra mdelay() calls;\nthe BUG_ON(pmd_none(*dst_pmd)) triggers.\r\n\r\nOn kernels newer than commit 0d940a9b270b (\u0026quot;mm/pgtable: allow\npte_offset_map[_lock]() to fail\u0026quot;), this can\u0026apos;t lead to anything worse than\na BUG_ON(), since the page table access helpers are actually designed to\ndeal with page tables concurrently disappearing; but on older kernels\n(\u0026lt;=6.4), I think we could probably theoretically race past the two\nBUG_ON() checks and end up treating a hugepage as a page table.\r\n\r\nThe second issue is that, as Qi Zheng pointed out, there are other types\nof huge PMDs that pmd_trans_huge() can\u0026apos;t catch: devmap PMDs and swap PMDs\n(in particular, migration PMDs).\r\n\r\nOn \u0026lt;=6.4, this is worse than the first issue: If mfill_atomic() runs on a\nPMD that contains a migration entry (which just requires winning a single,\nfairly wide race), it will pass the PMD to pte_offset_map_lock(), which\nassumes that the PMD points to a page table.\r\n\r\nBreakage follows: First, the kernel tries to take the PTE lock (which will\ncrash or maybe worse if there is no \u0026quot;struct page\u0026quot; for the address bits in\nthe migration entry PMD - I think at least on X86 there usually is no\ncorresponding \u0026quot;struct page\u0026quot; thanks to the PTE inversion mitigation, amd64\nlooks different).\r\n\r\nIf that didn\u0026apos;t crash, the kernel would next try to write a PTE into what\nit wrongly thinks is a page table.\r\n\r\nAs part of fixing these issues, get rid of the check for pmd_trans_huge()\nbefore __pte_alloc() - that\u0026apos;s redundant, we\u0026apos;re going to have to check for\nthat after the __pte_alloc() anyway.\r\n\r\nBackport note: pmdp_get_lockless() is pmd_read_atomic() in older kernels.(CVE-2024-46787)",
