Kernel crash via unpaired device-mapper suspend callbacks
Published Apr 17, 2024 · Updated Aug 5, 2026
Denial of service in affected Linux kernel device-mapper builds allows local users to crash the kernel through suspend operations. __dm_internal_resume omits target resume callbacks, so a later origin_postsuspend call removes an already-removed hash_list entry and corrupts the list. Reaching the device-mapper control path requires privileged local access; Siemens also reports local privilege escalation in one embedded subsystem.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=V3.1.0 <V3.1.5
