In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix UAF of struct file_lock in SMB2_LOCK deferred-lock cancellation When… (CVE-2026-64396)CVE-2026-64396 0 A use-after-free (UAF) vulnerability was identified and fixed in the Linux kernel's ksmbd component related to SMB2_LOCK deferred-lock cancellation. The issue occurs when asynchronous work handling deferred byte-range lock requests does not properly dequeue work items before freeing associated lock structures, leading to potential dereferencing of freed memory. This vulnerability could cause kernel memory corruption or instability. The fix restructures the cleanup logic to ensure proper serialization and removal of async work before freeing resources.
