AI-suggested

A security update for the kernel packages is available from Red Hat for Red Hat Enterprise Linux 10 and its extended support versions. Applying this update and rebooting the system is required to remediate the vulnerabilities. Refer to Red Hat's official advisory (RHSA-2025:15782) and update instructions at https://access.redhat.com/articles/11258 for detailed guidance. No additional mitigation steps are indicated beyond applying the official update and rebooting.

Description

In the Linux kernel, the following vulnerability has been resolved: ublk: make sure ubq->canceling is set when queue is frozen Now ublk driver depends on `ubq->canceling` for deciding if the request can be dispatched via uring_cmd & io_uring_cmd_complete_in_task(). Once ubq->canceling is set, the uring_cmd can be done via ublk_cancel_cmd() and io_uring_cmd_done(). So set ubq->canceling when queue is frozen, this way makes sure that the flag can be observed from ublk_queue_rq() reliably, and avoids use-after-free on uring_cmd.
