kernel: md: fix mddev uaf while iterating all_mddevs list

A flaw was discovered in the Linux kernel’s MD multiple device subsystem during iteration over the allmddevs list in functions such as mdnotifyreboot and mdexit. The code used listforeachentrysafe, but released locks before completing reference counting, allowing concurrent deletion and freeing o...

CVE-2025-22126

CVE-2025-22126 affects the Linux kernel md subsystem: a use-after-free can occur when iterating the mddev list during reboot/exit due to racing with deletions. The fix switches to list_for_each_entry and introduces a mddev_put_locked helper to prevent freeing the active mddev under the lock. Affe...
