What it is

In the Linux kernel, the following vulnerability has been resolved:

mm/damon/sysfs-schemes: call missing mem_cgroup_iter_break()

damon_sysfs_memcg_path_to_id() breaks mem_cgroup_iter() loop without

calling mem_cgroup_iter_break(). This leaks the cgroup reference. Fix

the issue by calling mem_cgroup_iter_break() before the break.

The issue was discovered [1] by Sashiko.
