Linux Kernel MemCG UAF Vulnerability
Description
In the Linux kernel, the following vulnerability has been resolved: mm: list_lru: fix UAF for memory cgroup The mem_cgroup_from_slab_obj() is supposed to be called under rcu lock or cgroup_mutex or others which could prevent returned memcg from being freed. Fix it by adding missing rcu read lock. Found by code inspection. [[email protected]: only grab rcu lock when necessary, per Vlastimil] Link: https://lkml.kernel.org/r/[email protected]
