CVE-2024-41054

Local kernel crash via UFS cleanup race

Published Jul 29, 2024 · Updated May 11, 2026

Race condition in the Linux kernel UFS core allows local users to crash the kernel during concurrent UFS command cleanup. The completion ISR can free a finished request and clear rq->mq_hctx while ufshcd_clear_cmd still passes that request to ufshcd_mcq_req_to_hwq, causing blk_mq_unique_tag to dereference NULL. Reachability requires local privileges and the affected UFS multi-circular-queue path; the bounded consequence is a kernel crash and service interruption.
