CVE-2024-35808

Kernel compromise via unlocked sync-thread teardown

Published May 17, 2024 · Updated Aug 5, 2026

Improper locking in Linux kernel md/dm-raid allows local users to compromise kernel memory through RAID control messages. raid_message() calls md_reap_sync_thread() without reconfig_mutex even though that teardown mutates mutex-protected fields. Reachability requires local low-privileged access and an active dm-raid sync thread; confidentiality, integrity, and availability are affected.
