CVE-2026-74375

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A deadlock can occur in the read error recovery path of raid1d and raid10d. This happens when a split md cloned bio is resubmitted while handling a read error, and the array is suspended before the md handle request() function acquires an active io reference via percpu ref tryget live(). Because the cloned bio already holds an active io reference, the attempt to acquire another reference through percpu ref tryget live() results in a deadlock during array suspension.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
