CVE-2026-72437

CVE-2026-72437 affects the Linux kernel RAID-1 path (md/raid1). When a read is retried and a pre-allocated r1_bio is used, if wait_read_barrier() fails for a REQ_NOWAIT read, the bio is completed but the existing r1_bio may be leaked. The vulnerability is a leak of pre-allocated r1_bio structures...
