In the Linux kernel, the following vulnerability has been resolved: mm/damon/dbgfs: fix \'struct pid\' leaks in \'dbgfs_target_ids_write()\' DAMON debugfs interface increases the reference counts of \'struct pid\'s for targets from the \'target_ids\' file write callback (\'dbgfs_target_ids_write()\'), but decreases the counts only in DAMON monitoring termination callback (\'dbgfs_before_terminate()\'). Therefore, when \'target_ids\' file is repeatedly written without DAMON monitoring start/termination, the reference count is not decreased and therefore memory for the \'struct pid\' cannot be freed. This commit fixes this issue by decreasing the reference counts when \'target_ids\' is written.
