If the walk\nraces with dm_table_destroy -> free_devices -> dm_put_table_device, there\nis access to invalid memory.\n\nFix this race by extending the lock over the list walk.","published":"2026-09-16T11:17:11.060","modified":"2026-09-16T11:17:11.060","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/00ad6f9ed27f91925d4d3fb7aab50a60d774f998"},{"type":"WEB","url":"https://git.kernel.org/stable/c/0ea6e5ad4a5817e91f11b4cc1e022e575ed2e7ca"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5380c7f6335cc6d77eb77d065105e81155c4d9d3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a1af1884c960b98c621b6fe2fea1216b78c02152"},{"type":"WEB","url":"https://git.kernel.org/stable/c/af1f32ccf8051f4691ced11feb452b9d13561727"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b02e35b81176c7d61dd441cc7a2e5c324a82444b"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-16T11:17:11.060"}}
