CVE-2026-74374

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

Description An issue exists in the md/raid1 and raid10 components where error-path detection fails when relying on r1 bio in raid1 or r10 bio->read slot in raid10, as these may be NULL or -1 after a failed bio is split and resubmitted. This failure prevents the error path from being recognized, causing memory allocations to incorrectly use GFP NOIO instead of (GFP NOIO | GFP HIGH), which can result in a deadlock during periods of memory pressure.

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