OESA-2024-2220 (CVE-2024-39482)

Vulnerability from osv_openeuler – Published: 2024-10-12 11:07 – Updated: 2026-08-06 11:07 – Source website

Summary

kernel security update

Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

bcache: fix variable length array abuse in btree_iter

btree_iter is used in two ways: either allocated on the stack with a fixed size MAX_BSETS, or from a mempool with a dynamic size based on the specific cache set. Previously, the struct had a fixed-length array of size MAX_BSETS which was indexed out-of-bounds for the dynamically-sized iterators, which causes UBSAN to complain.

This patch uses the same approach as in bcachefs's sort_iter and splits the iterator into a btree_iter with a flexible array member and a btree_iter_stack which embeds a btree_iter as well as a fixed-length data array.(CVE-2024-39482)

In the Linux kernel, the following vulnerability has been resolved:

ksmbd: discard write access to the directory open

may_open() does not allow a directory to be opened with the write access. However, some writing flags set by client result in adding write access on server, making ksmbd incompatible with FUSE file system. Simply, let's discard the write access when opening a directory.

In the Linux kernel, the following vulnerability has been resolved:

drm/nouveau/dispnv04: fix null pointer dereference in nv17_tv_get_ld_modes

In nv17_tv_get_ld_modes(), the return value of drm_mode_duplicate() is assigned to mode, which will lead to a possible NULL pointer dereference on failure of drm_mode_duplicate(). Add a check to avoid npd.(CVE-2024-41095)

In the Linux kernel, the following vulnerability has been resolved:

media: xc2028: avoid use-after-free in load_firmware_cb()

syzkaller reported use-after-free in load_firmware_cb() 1. The reason is because the module allocated a struct tuner in tuner_probe(), and then the module initialization failed, the struct tuner was released. A worker which created during module initialization accesses this struct tuner later, it caused use-after-free.

The process is as follows:

task-6504 worker_thread tuner_probe <= alloc dvb_frontend [2] ... request_firmware_nowait <= create a worker ... tuner_remove <= free dvb_frontend ... request_firmware_work_func <= the firmware is ready load_firmware_cb <= but now the dvb_frontend has been freed

To fix the issue, check the dvd_frontend in load_firmware_cb(), if it is null, report a warning and just return.

In the Linux kernel, the following vulnerability has been resolved:

sched/smt: Fix unbalance sched_smt_present dec/inc

I got the following warn report while doing stress test:

jump label: negative count! WARNING: CPU: 3 PID: 38 at kernel/jump_label.c:263 static_key_slow_try_dec+0x9d/0xb0 Call Trace: <TASK> __static_key_slow_dec_cpuslocked+0x16/0x70 sched_cpu_deactivate+0x26e/0x2a0 cpuhp_invoke_callback+0x3ad/0x10d0 cpuhp_thread_fun+0x3f5/0x680 smpboot_thread_fn+0x56d/0x8d0 kthread+0x309/0x400 ret_from_fork+0x41/0x70 ret_from_fork_asm+0x1b/0x30 </TASK>

Because when cpuset_cpu_inactive() fails in sched_cpu_deactivate(), the cpu offline failed, but sched_smt_present is decremented before calling sched_cpu_deactivate(), it leads to unbalanced dec/inc, so fix it by incrementing sched_smt_present in the error path.(CVE-2024-44958)

In the Linux kernel, the following vulnerability has been resolved:

drm/msm/dpu: cleanup FB if dpu_format_populate_layout fails

If the dpu_format_populate_layout() fails, then FB is prepared, but not cleaned up. This ends up leaking the pin_count on the GEM object and causes a splat during DRM file closure:

Patchwork: https://patchwork.freedesktop.org/patch/600714/(CVE-2024-44982)

In the Linux kernel, the following vulnerability has been resolved:

Input: MT - limit max slots

syzbot is reporting too large allocation at input_mt_init_slots(), for num_slots is supplied from userspace using ioctl(UI_DEV_CREATE).

Since nobody knows possible max slots, this patch chose 1024.(CVE-2024-45008)

In the Linux kernel, the following vulnerability has been resolved:

netem: fix return value if duplicate enqueue fails

There is a bug in netem_enqueue() introduced by commit 5845f706388a ("net: netem: fix skb length BUG_ON in __skb_to_sgvec") that can lead to a use-after-free.

This commit made netem_enqueue() always return NET_XMIT_SUCCESS when a packet is duplicated, which can cause the parent qdisc's q.qlen to be mistakenly incremented. When this happens qlen_notify() may be skipped on the parent during destruction, leaving a dangling pointer for some classful qdiscs like DRR.

There are two ways for the bug happen:

If the duplicated packet is dropped by rootq->enqueue() and then the original packet is also dropped.
If rootq->enqueue() sends the duplicated packet to a different qdisc and the original packet is dropped.

In both cases NET_XMIT_SUCCESS is returned even though no packets are enqueued at the netem qdisc.

The fix is to defer the enqueue of the duplicate packet until after the original packet has been guaranteed to return NET_XMIT_SUCCESS.(CVE-2024-45016)

In the Linux kernel, the following vulnerability has been resolved:

scsi: aacraid: Fix double-free on probe failure

aac_probe_one() calls hardware-specific init functions through the aac_driver_ident::init pointer, all of which eventually call down to aac_init_adapter().

If aac_init_adapter() fails after allocating memory for aac_dev::queues, it frees the memory but does not clear that member.

After the hardware-specific init function returns an error, aac_probe_one() goes down an error path that frees the memory pointed to by aac_dev::queues, resulting.in a double-free.(CVE-2024-46673)

In the Linux kernel, the following vulnerability has been resolved:

usb: dwc3: st: fix probed platform device ref count on probe error path

The probe function never performs any paltform device allocation, thus error path "undo_platform_dev_alloc" is entirely bogus. It drops the reference count from the platform device being probed. If error path is triggered, this will lead to unbalanced device reference counts and premature release of device resources, thus possible use-after-free when releasing remaining devm-managed resources.(CVE-2024-46674)

In the Linux kernel, the following vulnerability has been resolved:

ethtool: check device is present when getting link settings

A sysfs reader can race with a device reset or removal, attempting to read device state when the device is not actually present. eg:

state 5 is __LINK_STATE_START (0b1) and __LINK_STATE_NOCARRIER (0b100). The device is not present, note lack of __LINK_STATE_PRESENT (0b10).

This is the same sort of panic as observed in commit 4224cfd7fb65 ("net-sysfs: add check for netdevice being present to speed_show").

There are many other callers of __ethtool_get_link_ksettings() which don't have a device presence check.

Move this check into ethtool to protect all callers.(CVE-2024-46679)

In the Linux kernel, the following vulnerability has been resolved:

pktgen: use cpus_read_lock() in pg_net_init()

I have seen the WARN_ON(smp_processor_id() != cpu) firing in pktgen_thread_worker() during tests.

We must use cpus_read_lock()/cpus_read_unlock() around the for_each_online_cpu(cpu) loop.

While we are at it use WARN_ON_ONCE() to avoid a possible syslog flood.(CVE-2024-46681)

selinux,smack: don't bypass permissions check in inode_setsecctx hook

Marek Gresko reports that the root user on an NFS client is able to change the security labels on files on an NFS filesystem that is exported with root squashing enabled.

The end of the kerneldoc comment for __vfs_setxattr_noperm() states:

This function requires the caller to lock the inode's i_mutex before it
is executed. It also assumes that the caller will make the appropriate
permission checks.

nfsd_setattr() does do permissions checking via fh_verify() and nfsd_permission(), but those don't do all the same permissions checks that are done by security_inode_setxattr() and its related LSM hooks do.

Since nfsd_setattr() is the only consumer of security_inode_setsecctx(), simplest solution appears to be to replace the call to __vfs_setxattr_noperm() with a call to __vfs_setxattr_locked(). This fixes the above issue and has the added benefit of causing nfsd to recall conflicting delegations on a file when a client tries to change its security label.(CVE-2024-46695)

In the Linux kernel, the following vulnerability has been resolved:

KVM: arm64: Make ICC_SGI_EL1 undef in the absence of a vGICv3

On a system with a GICv3, if a guest hasn't been configured with GICv3 and that the host is not capable of GICv2 emulation, a write to any of the ICC_SGI_EL1 registers is trapped to EL2.

We therefore try to emulate the SGI access, only to hit a NULL pointer as no private interrupt is allocated (no GIC, remember?).

The obvious fix is to give the guest what it deserves, in the shape of a UNDEF exception.(CVE-2024-46707)

In that case, it must return an error code and the code, -ENOENT represents its state that the path of its parent is not existed yet.

VMCI: Fix use-after-free when removing resource in vmci_resource_remove()

When removing a resource from vmci_resource_table in vmci_resource_remove(), the search is performed using the resource handle by comparing context and resource fields.

It is possible though to create two resources with different types but same handle (same context and resource fields).

When trying to remove one of the resources, vmci_resource_remove() may not remove the intended one, but the object will still be freed as in the case of the datagram type in vmci_datagram_destroy_handle(). vmci_resource_table will still hold a pointer to this freed resource leading to a use-after-free vulnerability.

binder: fix UAF caused by offsets overwrite

Binder objects are processed and copied individually into the target buffer during transactions. Any raw data in-between these objects is copied as well. However, this raw data copy lacks an out-of-bounds check. If the raw data exceeds the data section size then the copy overwrites the offsets section. This eventually triggers an error that attempts to unwind the processed objects. However, at this point the offsets used to index these objects are now corrupted.

Unwinding with corrupted offsets can result in decrements of arbitrary nodes and lead to their premature release. Other users of such nodes are left with a dangling pointer triggering a use-after-free. This issue is made evident by the following KASAN report (trimmed):

Where pci_reset_bus() users are triggering unlocked secondary bus resets. Ironically pci_bus_reset(), several calls down from pci_reset_bus(), uses pci_bus_lock() before issuing the reset which locks everything but the bridge itself.

For the same motivation as adding:

bridge = pci_upstream_bridge(dev); if (bridge) pci_dev_lock(bridge);

to pci_reset_function() for the "bus" and "cxl_bus" reset cases, add pci_dev_lock() for @bus->self to pci_bus_lock().

wifi: mwifiex: Do not return unused priv in mwifiex_get_priv_by_id()

mwifiex_get_priv_by_id() returns the priv pointer corresponding to the bss_num and bss_type, but without checking if the priv is actually currently in use. Unused priv pointers do not have a wiphy attached to them which can lead to NULL pointer dereferences further down the callstack. Fix this by returning only used priv pointers which have priv->bss_mode set to something else than NL80211_IFTYPE_UNSPECIFIED.

Said NULL pointer dereference happened when an Accesspoint was started with wpa_supplicant -i mlan0 with this config:

In the Linux kernel, the following vulnerability has been resolved:

pci/hotplug/pnv_php: Fix hotplug driver crash on Powernv

The hotplug driver for powerpc (pci/hotplug/pnv_php.c) causes a kernel crash when we try to hot-unplug/disable the PCIe switch/bridge from the PHB.

The crash occurs because although the MSI data structure has been released during disable/hot-unplug path and it has been assigned with NULL, still during unregistration the code was again trying to explicitly disable the MSI which causes the NULL pointer dereference and kernel crash.

The patch fixes the check during unregistration path to prevent invoking pci_disable_msi/msix() since its data structure is already freed.(CVE-2024-46761)

In the Linux kernel, the following vulnerability has been resolved:

can: bcm: Remove proc entry when dev is unregistered.

syzkaller reported a warning in bcm_connect() below. [0]

The repro calls connect() to vxcan1, removes vxcan1, and calls connect() with ifindex == 0.

Calling connect() for a BCM socket allocates a proc entry. Then, bcm_sk(sk)->bound is set to 1 to prevent further connect().

However, removing the bound device resets bcm_sk(sk)->bound to 0 in bcm_notify().

The 2nd connect() tries to allocate a proc entry with the same name and sets NULL to bcm_sk(sk)->bcm_proc_read, leaking the original proc entry.

Since the proc entry is available only for connect()ed sockets, let's clean up the entry when the bound netdev is unregistered.

In the Linux kernel, the following vulnerability has been resolved:

udf: Avoid excessive partition lengths

Avoid mounting filesystems where the partition would overflow the 32-bits used for block number. Also refuse to mount filesystems where the partition length is so large we cannot safely index bits in a block bitmap.(CVE-2024-46777)

In the Linux kernel, the following vulnerability has been resolved:

nilfs2: protect references to superblock parameters exposed in sysfs

The superblock buffers of nilfs2 can not only be overwritten at runtime for modifications/repairs, but they are also regularly swapped, replaced during resizing, and even abandoned when degrading to one side due to backing device issues. So, accessing them requires mutual exclusion using the reader/writer semaphore "nilfs->ns_sem".

Some sysfs attribute show methods read this superblock buffer without the necessary mutual exclusion, which can cause problems with pointer dereferencing and memory access, so fix it.(CVE-2024-46780)

In the Linux kernel, the following vulnerability has been resolved:

nilfs2: fix missing cleanup on rollforward recovery error

In an error injection test of a routine for mount-time recovery, KASAN found a use-after-free bug.

It turned out that if data recovery was performed using partial logs created by dsync writes, but an error occurred before starting the log writer to create a recovered checkpoint, the inodes whose data had been recovered were left in the ns_dirty_files list of the nilfs object and were not freed.

Fix this issue by cleaning up inodes that have read the recovery data if the recovery routine fails midway before the log writer starts.(CVE-2024-46781)

In the Linux kernel, the following vulnerability has been resolved:

can: mcp251x: fix deadlock if an interrupt occurs during mcp251x_open

The mcp251x_hw_wake() function is called with the mpc_lock mutex held and disables the interrupt handler so that no interrupts can be processed while waking the device. If an interrupt has already occurred then waiting for the interrupt handler to complete will deadlock because it will be trying to acquire the same mutex.

CPU0 CPU1 ---- ---- mcp251x_open() mutex_lock(&priv->mcp_lock) request_threaded_irq() <interrupt> mcp251x_can_ist() mutex_lock(&priv->mcp_lock) mcp251x_hw_wake() disable_irq() <-- deadlock

Use disable_irq_nosync() instead because the interrupt handler does everything while holding the mutex so it doesn't matter if it's still running.(CVE-2024-46791)
