CVE-2026-72440

CVE-2026-72440 affects the Linux kernel md/raid1 code. The issue arises from writes_pending and barrier reference leaks when write failures occur in raid1_write_request(). raid1_make_request() starts a writes_pending reference via md_write_start() and may skip md_write_end() on certain failure pa...

CVE-2026-72437 md/raid1: free r1_bio when REQ_NOWAIT is set and read would block on retry

In the Linux kernel, the following vulnerability has been resolved: md/raid1: free r1bio when REQNOWAIT is set and read would block on retry When a read is retried, raid1readrequest may be called with a pre-allocated r1bio. If waitreadbarrier fails for a REQNOWAIT read, the bio is completed and t...

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...
