CVE-2023-53510

Local kernel compromise via duplicate UFS submission

Published Oct 1, 2025 · Updated Oct 1, 2025

Memory corruption in the Linux UFS core allows local users to compromise the kernel by forcing a timed-out SCSI command to be resubmitted. When ufshcd_queuecommand reuses the same tag before completion, it rewrites an active transfer descriptor and leaves stale DMA state that can corrupt reused kernel pages. An ordinary local account able to generate I/O on UFS-backed storage can trigger the path without user interaction, leading to kernel memory disclosure, control-flow hijack, or a storage hang.
