CVE-2022-0480 is a Linux kernel resource-exhaustion flaw in the filelock_init function. Memory cgroups (memcg) do not limit the number of POSIX file locks that processes can create, allowing lock allocations to evade the resource controls intended to constrain a cgroup's memory consumption. A local process can consequently consume host memory through excessive POSIX file-lock creation.
