{"id":"AZL-96063","summary":"CVE-2026-72438 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmd/raid10: fix writes_pending and barrier reference leaks on discard failures\n\nraid10_make_request() acquires a writes_pending reference with\nmd_write_start() before calling raid10_handle_discard(). Several failure\npaths in raid10_handle_discard() complete the bio and return without\nreleasing the corresponding reference, causing md_write_end() to be\nskipped.\n\nCall md_write_end() before returning from these failure paths to keep\nwrites_pending accounting balanced.\n\nAdditionally, discard split allocation failures can occur after\nwait_barrier() succeeds. Those paths return without calling\nallow_barrier(), leaking the associated barrier reference.\n\nRelease the barrier before returning from those paths.","modified":"2026-09-04T05:27:10Z","published":"2026-08-15T06:22:17Z","upstream":["CVE-2026-72438"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72438"}],"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-96063.json"}}],"schema_version":"1.9.0"}
