When a cgroup is being destroyed, cgroup_rstat_flush() is only called at css_release_work_fn(), which is called when the blkcg reference count reaches 0. This circular dependency will prevent blkcg and some blkgs from being freed after they are made offline. This issue may allow an attacker with a local access to cause system instability, such as an out of memory error."},{"lang":"es","value":"Se encontró un fallo en la ruta de destrucción de blkgs en block/blk-cgroup.c en el kernel de Linux, lo que provocó un problema de pérdida de memoria de cgroup blkio.
