CVE-2026-23254 (GCVE-0-2026-23254)

Vulnerability from cvelistv5 – Published: 2026-03-18 17:41 – Updated: 2026-05-23 16:04

Title

net: gro: fix outer network offset

Summary

In the Linux kernel, the following vulnerability has been resolved: net: gro: fix outer network offset The udp GRO complete stage assumes that all the packets inserted the RX have the `encapsulation` flag zeroed. Such assumption is not true, as a few H/W NICs can set such flag when H/W offloading the checksum for an UDP encapsulated traffic, the tun driver can inject GSO packets with UDP encapsulation and the problematic layout can also be created via a veth based setup. Due to the above, in the problematic scenarios, udp4_gro_complete() uses the wrong network offset (inner instead of outer) to compute the outer UDP header pseudo checksum, leading to csum validation errors later on in packet processing. Address the issue always clearing the encapsulation flag at GRO completion time. Such flag will be set again as needed for encapsulated packets by udp_gro_complete().

Title

cxl/mbox: validate payload size before accessing contents in cxl_payload_from_user_allowed()

Summary

In the Linux kernel, the following vulnerability has been resolved: cxl/mbox: validate payload size before accessing contents in cxl_payload_from_user_allowed() cxl_payload_from_user_allowed() casts and dereferences the input payload without first verifying its size. When a raw mailbox command is sent with an undersized payload (ie: 1 byte for CXL_MBOX_OP_CLEAR_LOG, which expects a 16-byte UUID), uuid_equal() reads past the allocated buffer, triggering a KASAN splat: BUG: KASAN: slab-out-of-bounds in memcmp+0x176/0x1d0 lib/string.c:683 Read of size 8 at addr ffff88810130f5c0 by task syz.1.62/2258 CPU: 2 UID: 0 PID: 2258 Comm: syz.1.62 Not tainted 6.19.0-dirty #3 PREEMPT(voluntary) Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.17.0-0-gb52ca86e094d-prebuilt.qemu.org 04/01/2014 Call Trace: <TASK> __dump_stack lib/dump_stack.c:94 [inline] dump_stack_lvl+0xab/0xe0 lib/dump_stack.c:120 print_address_description mm/kasan/report.c:378 [inline] print_report+0xce/0x650 mm/kasan/report.c:482 kasan_report+0xce/0x100 mm/kasan/report.c:595 memcmp+0x176/0x1d0 lib/string.c:683 uuid_equal include/linux/uuid.h:73 [inline] cxl_payload_from_user_allowed drivers/cxl/core/mbox.c:345 [inline] cxl_mbox_cmd_ctor drivers/cxl/core/mbox.c:368 [inline] cxl_validate_cmd_from_user drivers/cxl/core/mbox.c:522 [inline] cxl_send_cmd+0x9c0/0xb50 drivers/cxl/core/mbox.c:643 __cxl_memdev_ioctl drivers/cxl/core/memdev.c:698 [inline] cxl_memdev_ioctl+0x14f/0x190 drivers/cxl/core/memdev.c:713 vfs_ioctl fs/ioctl.c:51 [inline] __do_sys_ioctl fs/ioctl.c:597 [inline] __se_sys_ioctl fs/ioctl.c:583 [inline] __x64_sys_ioctl+0x18e/0x210 fs/ioctl.c:583 do_syscall_x64 arch/x86/entry/syscall_64.c:63 [inline] do_syscall_64+0xa8/0x330 arch/x86/entry/syscall_64.c:94 entry_SYSCALL_64_after_hwframe+0x77/0x7f RIP: 0033:0x7fdaf331ba79 Code: ff ff c3 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 40 00 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 c7 c1 a8 ff ff ff f7 d8 64 89 01 48 RSP: 002b:00007fdaf1d77038 EFLAGS: 00000246 ORIG_RAX: 0000000000000010 RAX: ffffffffffffffda RBX: 00007fdaf3585fa0 RCX: 00007fdaf331ba79 RDX: 00002000000001c0 RSI: 00000000c030ce02 RDI: 0000000000000003 RBP: 00007fdaf33749df R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000000000 R11: 0000000000000246 R12: 0000000000000000 R13: 00007fdaf3586038 R14: 00007fdaf3585fa0 R15: 00007ffced2af768 </TASK> Add 'in_size' parameter to cxl_payload_from_user_allowed() and validate the payload is large enough.

net: mvpp2: guard flow control update with global_tx_fc in buffer switching

Summary

In the Linux kernel, the following vulnerability has been resolved: net: mvpp2: guard flow control update with global_tx_fc in buffer switching mvpp2_bm_switch_buffers() unconditionally calls mvpp2_bm_pool_update_priv_fc() when switching between per-cpu and shared buffer pool modes. This function programs CM3 flow control registers via mvpp2_cm3_read()/mvpp2_cm3_write(), which dereference priv->cm3_base without any NULL check. When the CM3 SRAM resource is not present in the device tree (the third reg entry added by commit 60523583b07c ("dts: marvell: add CM3 SRAM memory to cp11x ethernet device tree")), priv->cm3_base remains NULL and priv->global_tx_fc is false. Any operation that triggers mvpp2_bm_switch_buffers(), for example an MTU change that crosses the jumbo frame threshold, will crash: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 Mem abort info: ESR = 0x0000000096000006 EC = 0x25: DABT (current EL), IL = 32 bits pc : readl+0x0/0x18 lr : mvpp2_cm3_read.isra.0+0x14/0x20 Call trace: readl+0x0/0x18 mvpp2_bm_pool_update_fc+0x40/0x12c mvpp2_bm_pool_update_priv_fc+0x94/0xd8 mvpp2_bm_switch_buffers.isra.0+0x80/0x1c0 mvpp2_change_mtu+0x140/0x380 __dev_set_mtu+0x1c/0x38 dev_set_mtu_ext+0x78/0x118 dev_set_mtu+0x48/0xa8 dev_ifsioc+0x21c/0x43c dev_ioctl+0x2d8/0x42c sock_ioctl+0x314/0x378 Every other flow control call site in the driver already guards hardware access with either priv->global_tx_fc or port->tx_fc. mvpp2_bm_switch_buffers() is the only place that omits this check. Add the missing priv->global_tx_fc guard to both the disable and re-enable calls in mvpp2_bm_switch_buffers(), consistent with the rest of the driver.

Title

net: macb: fix use-after-free access to PTP clock

Summary

In the Linux kernel, the following vulnerability has been resolved: net: macb: fix use-after-free access to PTP clock PTP clock is registered on every opening of the interface and destroyed on every closing. However it may be accessed via get_ts_info ethtool call which is possible while the interface is just present in the kernel.

The trigger can be repeated while the stale pointer remains.\nPR:L - A basic local user can issue the ETHTOOL_GET_TS_INFO query path, which ethtool explicitly allows without CAP_NET_ADMIN. Interface cycling is privileged, but the stale state can exist after normal system management, so the higher-severity defensible choice is PR:L.\nUI:N - No victim action is required after the affected macb/GEM interface exists in the vulnerable state. The attacker invokes the local query directly.\nS:U - The bug is in a kernel network driver and impacts the same kernel security authority. It is not a guest-to-host, IOMMU, or other cross-scope boundary bypass.\nC:H - This is a kernel heap use-after-free of struct ptp_clock reached through a stale driver pointer. Under the kernel scoring guidance, UAFs are treated as high confidentiality impact because freed object reuse can enable memory disclosure primitives.\nI:H - Although the observed crash path is a stale read of the PTP clock index, the underlying bug is a kernel heap UAF. Under the required kernel guidance, UAFs are scored as high integrity impact because heap reuse can be leveraged toward control-flow or write primitives.\nA:H - The reported KASAN trace shows a use-after-free in ptp_clock_index(), and such kernel UAFs can cause oops/panic or repeated system crashes.

CVE-2026-31401 (GCVE-0-2026-31401)

Vulnerability from cvelistv5 – Published: 2026-04-03 15:16 – Updated: 2026-08-05 12:22

Title

HID: bpf: prevent buffer overflow in hid_hw_request

Summary

In the Linux kernel, the following vulnerability has been resolved: HID: bpf: prevent buffer overflow in hid_hw_request right now the returned value is considered to be always valid. However, when playing with HID-BPF, the return value can be arbitrary big, because it's the return value of dispatch_hid_bpf_raw_requests(), which calls the struct_ops and we have no guarantees that the value makes sense.

Severity

7.8 (High)

As memory corruption, it is also potentially usable to build stronger read primitives.\nI:H - The same unchecked return value is used as the length for `memcpy()` into the caller-provided BPF memory buffer, producing an out-of-bounds kernel write. Such kernel memory corruption is defensibly capable of arbitrary modification or control-flow compromise.\nA:H - A large attacker-controlled copy length can corrupt kernel memory or fault during the copy, causing an oops, panic, or system crash."

Title

ext4: fix use-after-free in update_super_work when racing with umount

Summary

In the Linux kernel, the following vulnerability has been resolved: ext4: fix use-after-free in update_super_work when racing with umount Commit b98535d09179 ("ext4: fix bug_on in start_this_handle during umount filesystem") moved ext4_unregister_sysfs() before flushing s_sb_upd_work to prevent new error work from being queued via /proc/fs/ext4/xx/mb_groups reads during unmount. However, this introduced a use-after-free because update_super_work calls ext4_notify_error_sysfs() -> sysfs_notify() which accesses the kobject's kernfs_node after it has been freed by kobject_del() in ext4_unregister_sysfs(): update_super_work ext4_put_super ----------------- -------------- ext4_unregister_sysfs(sb) kobject_del(&sbi->s_kobj) __kobject_del() sysfs_remove_dir() kobj->sd = NULL sysfs_put(sd) kernfs_put() // RCU free ext4_notify_error_sysfs(sbi) sysfs_notify(&sbi->s_kobj) kn = kobj->sd // stale pointer kernfs_get(kn) // UAF on freed kernfs_node ext4_journal_destroy() flush_work(&sbi->s_sb_upd_work) Instead of reordering the teardown sequence, fix this by making ext4_notify_error_sysfs() detect that sysfs has already been torn down by checking s_kobj.state_in_sysfs, and skipping the sysfs_notify() call in that case. A dedicated mutex (s_error_notify_mutex) serializes ext4_notify_error_sysfs() against kobject_del() in ext4_unregister_sysfs() to prevent TOCTOU races where the kobject could be deleted between the state_in_sysfs check and the sysfs_notify() call.

CVE-2026-31448 (GCVE-0-2026-31448)

Vulnerability from cvelistv5 – Published: 2026-04-22 13:53 – Updated: 2026-09-08 08:47

Title

ext4: avoid infinite loops caused by residual data

Summary

In the Linux kernel, the following vulnerability has been resolved: ext4: avoid infinite loops caused by residual data On the mkdir/mknod path, when mapping logical blocks to physical blocks, if inserting a new extent into the extent tree fails (in this example, because the file system disabled the huge file feature when marking the inode as dirty), ext4_ext_map_blocks() only calls ext4_free_blocks() to reclaim the physical block without deleting the corresponding data in the extent tree. This causes subsequent mkdir operations to reference the previously reclaimed physical block number again, even though this physical block is already being used by the xattr block. Therefore, a situation arises where both the directory and xattr are using the same buffer head block in memory simultaneously. The above causes ext4_xattr_block_set() to enter an infinite loop about "inserted" and cannot release the inode lock, ultimately leading to the 143s blocking problem mentioned in [1]. If the metadata is corrupted, then trying to remove some extent space can do even more harm. Also in case EXT4_GET_BLOCKS_DELALLOC_RESERVE was passed, remove space wrongly update quota information. Jan Kara suggests distinguishing between two cases: 1) The error is ENOSPC or EDQUOT - in this case the filesystem is fully consistent and we must maintain its consistency including all the accounting. However these errors can happen only early before we've inserted the extent into the extent tree. So current code works correctly for this case. 2) Some other error - this means metadata is corrupted. We should strive to do as few modifications as possible to limit damage. So I'd just skip freeing of allocated blocks. [1] INFO: task syz.0.17:5995 blocked for more than 143 seconds.

This causes subsequent mkdir operations to reference\nthe previously reclaimed physical block number again, even though this\nphysical block is already being used by the xattr block. Therefore, a\nsituation arises where both the directory and xattr are using the same\nbuffer head block in memory simultaneously.\n\nThe above causes ext4_xattr_block_set() to enter an infinite loop about\n\"inserted\" and cannot release the inode lock, ultimately leading to the\n143s blocking problem mentioned in [1].\n\nIf the metadata is corrupted, then trying to remove some extent space\ncan do even more harm. Also in case EXT4_GET_BLOCKS_DELALLOC_RESERVE\nwas passed, remove space wrongly update quota information.\nJan Kara suggests distinguishing between two cases:\n\n1) The error is ENOSPC or EDQUOT - in this case the filesystem is fully\nconsistent and we must maintain its consistency including all the\naccounting. However these errors can happen only early before we\u0027ve\ninserted the extent into the extent tree. So current code works correctly\nfor this case.\n\n2) Some other error - this means metadata is corrupted. We should strive to\ndo as few modifications as possible to limit damage.

CVE-2026-31454 (GCVE-0-2026-31454)

Vulnerability from cvelistv5 – Published: 2026-04-22 13:53 – Updated: 2026-08-05 12:22

Title

xfs: save ailp before dropping the AIL lock in push callbacks

Summary

In the Linux kernel, the following vulnerability has been resolved: xfs: save ailp before dropping the AIL lock in push callbacks In xfs_inode_item_push() and xfs_qm_dquot_logitem_push(), the AIL lock is dropped to perform buffer IO. Once the cluster buffer no longer protects the log item from reclaim, the log item may be freed by background reclaim or the dquot shrinker. The subsequent spin_lock() call dereferences lip->li_ailp, which is a use-after-free. Fix this by saving the ailp pointer in a local variable while the AIL lock is held and the log item is guaranteed to be valid.

Severity

7.8 (High)

XFS is not user-namespace mountable, but exploiting an already mounted writable XFS filesystem does not require real root.\nUI:N - No victim action is needed beyond the attacker issuing local filesystem operations. The vulnerable callback runs asynchronously in the per-mount xfsaild kernel thread.\nS:U - The impact remains within the same kernel security authority. This is a standard local kernel memory-safety issue, not a guest-to-host or cross-sandbox boundary bypass by itself.\nC:H - The bug is a kernel slab use-after-free of XFS log-item memory after reclaim can free the object. Conservatively, kernel UAFs can be shaped for memory disclosure, so confidentiality impact is high.\nI:H - The stale log item is dereferenced after free and used to reacquire a spinlock through data read from freed memory, making this a plausible kernel memory corruption primitive. Following the required overestimate rule for UAFs, integrity impact is high.\nA:H - The observed failure is a KASAN slab-use-after-free in xfs_inode_item_push from xfsaild, which can crash or destabilize the kernel.

CVE-2026-31455 (GCVE-0-2026-31455)

Vulnerability from cvelistv5 – Published: 2026-04-22 13:53 – Updated: 2026-05-11 22:09

Title

xfs: stop reclaim before pushing AIL during unmount

Summary

In the Linux kernel, the following vulnerability has been resolved: xfs: stop reclaim before pushing AIL during unmount The unmount sequence in xfs_unmount_flush_inodes() pushed the AIL while background reclaim and inodegc are still running. This is broken independently of any use-after-free issues - background reclaim and inodegc should not be running while the AIL is being pushed during unmount, as inodegc can dirty and insert inodes into the AIL during the flush, and background reclaim can race to abort and free dirty inodes. Reorder xfs_unmount_flush_inodes() to stop inodegc and cancel background reclaim before pushing the AIL. Stop inodegc before cancelling m_reclaim_work because the inodegc worker can re-queue m_reclaim_work via xfs_inodegc_set_reclaimable.
