04 Feb 2026 — In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix recvmsg() unconditional requeue If rxrpc_recvmsg() fails because MSG_DONTWAIT was specified but the call at the front of the recvmsg queue already has its mutex locked, it requeues the call - whether or not the call is already queued. The call may be on the queue because MSG_PEEK was also passed and so the call was not dequeued or because the I/O thread requeued it. The unconditional requeue may then corrupt the recvmsg queue, le... • https://git.kernel.org/stable/c/540b1c48c37ac0ad66212004db21e1ff7e2d78be •

04 Feb 2026 — In the Linux kernel, the following vulnerability has been resolved: uacce: ensure safe queue release with state management Directly calling `put_queue` carries risks since it cannot guarantee that resources of `uacce_queue` have been fully released beforehand. So adding a `stop_queue` operation for the UACCE_CMD_PUT_Q command and leaving the `put_queue` operation to the final resource release ensures safety. Queue states are defined as follows: - UACCE_Q_ZOMBIE: Initial state - UACCE_Q_INIT: After opening `... • https://git.kernel.org/stable/c/015d239ac0142ad0e26567fd890ef8d171f13709 •
