CVE-2026-89631

In the Linux kernel, the following vulnerability has been resolved: smb: client: reject a tree connect response whose byte count is too small CIFSTCon() bounds its strnlen() over the byte area with the server's ByteCount minus two, which for ByteCount 0 or 1 goes negative as an int and converts to a huge size_t. The later subtraction wraps the __u16 bytes_left, and that is what bounds cifs_strndup_from_utf16(): a bound of up to 65535 against a ~16 KB cifs_req_poolp object runs off the end of the slab object, and the bytes reach userspace through tcon->nativeFileSystem in /proc/fs/cifs/DebugData. Reject a byte area too small for what the parser consumes. Two bytes is the least it can consume, and no conformant response carries fewer. The new trace point is the 129th smb_eio_trace entry, which __mode(byte) cannot represent, so the attribute goes with it.

The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:ALSA: caiaq: Use snd_card_free_when_closed() at disconnectionThe USB disconnect callback is supposed to be short and not too-longwaiting. OTOH, the current code uses snd_card_free() atdisconnection, but this waits for the close of all used fds, hence itcan take long. It eventually blocks the upper layer USB ioctls, whichmay trigger a soft lockup.An easy workaround is to replace snd_card_free() withsnd_card_free_when_closed(). This variant returns immediately whilethe release of resources is done asynchronously by the card devicerelease at the last close.This patch also splits the code to the disconnect and the free phases;the former is called immediately at the USB disconnect callback whilethe latter is called from the card destructor.(CVE-2024-56531)

In the Linux kernel, the following vulnerability has been resolved:xsk: fix OOB map writes when deleting elementsJordy says: In the xsk_map_delete_elem function an unsigned integer(map->max_entries) is compared with a user-controlled signed integer(k). Due to implicit type conversion, a large unsigned value formap->max_entries can bypass the intended bounds check: if (k >= map->max_entries) return -EINVAL;This allows k to hold a negative value (between -2147483648 and -2),which is then used as an array index in m->xsk_map[k], which resultsin an out-of-bounds access. spin_lock_bh(&m->lock); map_entry = &m->xsk_map[k]; // Out-of-bounds map_entry old_xs = unrcu_pointer(xchg(map_entry, NULL)); // Oob write if (old_xs) xsk_map_sock_delete(old_xs, map_entry); spin_unlock_bh(&m->lock);The xchg operation can then be used to cause an out-of-bounds write.Moreover, the invalid map_entry passed to xsk_map_sock_delete can leadto further memory corruption. It indeed results in following splat:[76612.897343] BUG: unable to handle page fault for address: ffffc8fc2e461108[76612.904330] #PF: supervisor write access in kernel mode[76612.909639] #PF: error_code(0x0002) - not-present page[76612.914855] PGD 0 P4D 0[76612.917431] Oops: Oops: 0002 [#1] PREEMPT SMP[76612.921859] CPU: 11 UID: 0 PID: 10318 Comm: a.out Not tainted 6.12.0-rc1+ #470[76612.929189] Hardware name: Intel Corporation S2600WFT/S2600WFT, BIOS SE5C620.86B.02.01.0008.031920191559 03/19/2019[76612.939781] RIP: 0010:xsk_map_delete_elem+0x2d/0x60[76612.944738] Code: 00 00 41 54 55 53 48 63 2e 3b 6f 24 73 38 4c 8d a7 f8 00 00 00 48 89 fb 4c 89 e7 e8 2d bf 05 00 48 8d b4 eb 00 01 00 00 31 ff <48> 87 3e 48 85 ff 74 05 e8 16 ff ff ff 4c 89 e7 e8 3e bc 05 00 31[76612.963774] RSP: 0018:ffffc9002e407df8 EFLAGS: 00010246[76612.969079] RAX: 0000000000000000 RBX: ffffc9002e461000 RCX: 0000000000000000[76612.976323] RDX: 0000000000000001 RSI: ffffc8fc2e461108 RDI: 0000000000000000[76612.983569] RBP: ffffffff80000001 R08: 0000000000000000 R09: 0000000000000007[76612.990812] R10: ffffc9002e407e18 R11: ffff888108a38858 R12: ffffc9002e4610f8[76612.998060] R13: ffff888108a38858 R14: 00007ffd1ae0ac78 R15: ffffc9002e4610c0[76613.005303] FS: 00007f80b6f59740(0000) GS:ffff8897e0ec0000(0000) knlGS:0000000000000000[76613.013517] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[76613.019349] CR2: ffffc8fc2e461108 CR3: 000000011e3ef001 CR4: 00000000007726f0[76613.026595] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000[76613.033841] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400[76613.041086] PKRU: 55555554[76613.043842] Call Trace:[76613.046331] <TASK>[76613.048468] ? __die+0x20/0x60[76613.051581] ? page_fault_oops+0x15a/0x450[76613.055747] ? search_extable+0x22/0x30[76613.059649] ? search_bpf_extables+0x5f/0x80[76613.063988] ? exc_page_fault+0xa9/0x140[76613.067975] ? asm_exc_page_fault+0x22/0x30[76613.072229] ? xsk_map_delete_elem+0x2d/0x60[76613.076573] ? xsk_map_delete_elem+0x23/0x60[76613.080914] …

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

smb: client: reject a tree connect response whose byte count is too small

CIFSTCon() bounds its strnlen() over the byte area with the server's ByteCount minus two, which for ByteCount 0 or 1 goes negative as an int and converts to a huge size_t. The later subtraction wraps the __u16 bytes_left, and that is what bounds cifs_strndup_from_utf16(): a bound of up to 65535 against a ~16 KB cifs_req_poolp object runs off the end of the slab object, and the bytes reach userspace through tcon->nativeFileSystem in /proc/fs/cifs/DebugData.

Reject a byte area too small for what the parser consumes. Two bytes is the least it can consume, and no conformant response carries fewer. The new trace point is the 129th smb_eio_trace entry, which __mode(byte) cannot represent, so the attribute goes with it.

It was discovered that the io_uring subsystem in the Linux kernel did not properly handle canceled task work when processing certain wait operations, leading to the operation being performed in the wrong task context. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2026-81010)
