kernel: Linux kernel: Denial of Service via deadlock in block layer sysfs store callbacks

A flaw was found in the Linux kernel. A local user could exploit a vulnerability where freezing the request queue within certain sysfs store callbacks can lead to a deadlock. This issue may occur when combined with the device-mapper multipath dm-multipath driver and the queueifnopath option, or...

CVE-2025-71117

CVE-2025-71117 corresponds to a Linux kernel fix that removes queue freezing from several sysfs store callbacks to prevent deadlocks (notably with dm-multipath and the queue_if_no_path option). Affected sysfs attributes include io_poll_delay, io_timeout, nomerges, read_ahead_kb, and rq_affinity. ...
