CVE-2024-0443
Full vulnerability record from the local CVENow database.
Description
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.

"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. Cuando se destruye un cgroup, cgroup_rstat_flush() solo se llama en css_release_work_fn(), que se llama cuando el recuento de referencias de blkcg llega a 0. Esta dependencia circular evitará que blkcg y algunos blkgs se liberen después de desconectarse. Este problema puede permitir que un atacante con acceso local cause inestabilidad en el sistema, como un error de falta de memoria."
