CVE-2026-72437

A flaw was found in the Linux kernel's md/raid1 component. When a read operation is retried with the REQNOWAIT flag set, and the waitreadbarrier function fails, a pre-allocated r1bio structure may not be properly freed. This resource leak can accumulate over time, potentially leading to a denial ...
