AI-suggested
A patch is available and should be applied to affected Linux kernel versions. The fix replaces the unsafe direct call to md_reap_sync_thread() with stop_sync_thread() to avoid deadlocks and unsafe concurrency. Users should update their kernels to versions including this fix.
Description
A vulnerability in the Linux kernel's md/dm-raid subsystem was resolved. The issue involved unsafe direct calls to md_reap_sync_thread() from raid_message() without holding the reconfig_mutex, risking data corruption or instability. The fix replaces this call with stop_sync_thread() to safely unregister the sync_thread, avoiding deadlocks. This vulnerability affects multiple Linux kernel versions prior to 6.8.0-35.35 and several specific older versions. A patch is available to address this issue.
