Vulnerability from cvelistv5

Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
A flaw was found in the blkgs destruction path in block/blk-cgroup.c in the Linux kernel, leading to a cgroup blkio memory leakage problem. 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.

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 encontr\u00f3 un fallo en la ruta de destrucci\u00f3n de blkgs en block/blk-cgroup.c en el kernel de Linux, lo que provoc\u00f3 un problema de p\u00e9rdida de memoria de cgroup blkio.
