CVE-2026-53198

In the Linux kernel ksmbd, CVE-2026-53198 describes a use-after-free in a deferred file_lock tied to SMB2_CANCEL handling. A deferred byte-range lock registers async work via setup_async_work() with a cancel_fn and cancel_argv[0] pointing at the file_lock. If the SMB2_CANCEL path frees the file_l...

In the Linux kernel, the following vulnerability has been resolved: xfrm: iptfs: fix ABBA deadlock in iptfsdestroystate iptfsdestroystate calls hrtimercancel while holding a spinlock that the timer callback also acquires, leading to an ABBA deadlock on SMP systems. For the output timer iptfstimer...

CVE-2026-53197

The CVE-2026-53197 entry documents a Linux kernel ABBA deadlock in xfrm/iptfs due to iptfs_destroy_state() calling hrtimer_cancel() while holding locks that the timer callbacks also acquire. The fix implemented is to call hrtimer_cancel() before acquiring either the output timer lock (x->lock)...

In the Linux kernel, the following vulnerability has been resolved: fs/mbcache: cancel shrink work before destroying the cache mbcachedestroy calls shrinkerfree and then frees all cache entries and the cache itself, but it does not cancel the pending cshrinkwork work item first. If...

CVE-2026-53129

The CVE-2026-53129 fix in the Linux kernel addresses a use-after-free in the mb_cache shrink path. Specifically, mb_cache_destroy() previously freed cache memory after scheduling c_shrink_work, but did not cancel the pending work item, risking mb_cache_shrink_worker() accessing freed memory if th...

CVE-2026-52933

A flaw was found in the Linux kernel's iouring/poll component. A logic error exists in the iopollgetownership function due to an incorrect signed comparison. This flaw prevents the necessary slowpath from being triggered when the IOPOLLCANCELFLAG is set, potentially leading to unexpected behavior...

CVE-2026-52933

CVE-2026-52933 affects the Linux kernel’s io_uring/poll path. The vulnerability stems from a signed comparison in io_poll_get_ownership(): it compares an atomic_read(&req->poll_refs) against IO_POLL_REF_BIAS using signed arithmetic. If the IO_POLL_CANCEL_FLAG (BIT(31)) is set, the read value b...
