{"id":"AZL-96588","summary":"CVE-2026-72440 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmd/raid1: fix writes_pending and barrier reference leaks on write failures\n\nraid1_make_request() acquires a writes_pending reference with\nmd_write_start() before calling raid1_write_request(). Several failure\npaths in raid1_write_request() complete the bio and return without\nreaching the normal write completion path, causing the corresponding\nmd_write_end() to be skipped.\n\nMake raid1_write_request() return a status indicating whether the write\nrequest was successfully queued. This allows raid1_make_request() to\ncall md_write_end() when raid1_write_request() fails.\n\nAdditionally, if wait_blocked_rdev() fails after wait_barrier()\nsucceeds, the associated barrier reference is not released.\n\nCall allow_barrier() before returning from that path to keep the barrier\naccounting balanced.","modified":"2026-08-31T05:26:27Z","published":"2026-08-15T06:22:17Z","upstream":["CVE-2026-72440"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72440"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-96588.json"}}],"schema_version":"1.9.0"}
