  "description": "In the Linux kernel, the following vulnerability has been resolved:  mm/damon/dbgfs: protect targets destructions with kdamond_lock  DAMON debugfs interface iterates current monitoring targets in \u0027dbgfs_target_ids_read()\u0027 while holding the corresponding \u0027kdamond_lock\u0027.  However, it also destructs the monitoring targets in \u0027dbgfs_before_terminate()\u0027 without holding the lock.  This can result in a use_after_free bug.  This commit avoids the race by protecting the destruction with the corresponding \u0027kdamond_lock\u0027.",
