The result is that the table is destroyed without\ncalling the postsuspend method.\n\nDm targets expect that they may be removed only after the postsuspend\nmethod method was called. If we break this expectation, it can cause\nmisbehavior in various targets. For example - in the dm-integrity target,\nthe reboot notifier is not unregistered, leading to use-after-free.\n\nFix this bug by refusing to resume if the device is being destroyed.","published":"2026-09-16T11:17:10.933","modified":"2026-09-16T11:17:10.933","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1ede2bce2bd640605df83db1356fd727159bc9ed"},{"type":"WEB","url":"https://git.kernel.org/stable/c/36177beff2a9df035991ad8d16ccf8d363ed93ee"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3b59530b14fde693e41d8e39bc326df6cbf07b76"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3f04e6520d9a53adb1d1daf4dc5d31a60fc77d1f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/44b43ec132f1cf3275ecc182d0c82f50c3c4c3d5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/94380ecd5ff9b2a2b9f6e8a0b5c465159ccfaf71"},{"type":"WEB","url":"https://git.kernel.org/stable/c/94f3d399c1ddba763c1c5a6501f7375d533d789f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9757367bcf1d5d2c50b94d005abca21f3eedd7c3"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-16T11:17:10.933"}}
