Description

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.

Affected configurations

• linux linux kernel (>= 6.3 < 6.6.142) • linux linux kernel (>= 6.7 < 6.12.92) • linux linux kernel (>= 6.13 < 6.18.34) • linux linux kernel (>= 6.19 < 7.0.11) • linux linux kernel 7.1
