CVE-2024-0443

Es besteht eine Schwachstelle im Linux-Kernel. Dieser Fehler besteht im blkgs-Zerstörungspfad in der Komponente block/blk-cgroup.c, der zu einem Speicherleck führt, was zu einer Instabilität des Systems führt, z. B. zu einem Out-of-Memory-Fehler. Ein lokaler Angreifer kann diese Schwachstelle ausnutzen, um einen Denial-of-Service-Zustand zu verursachen.
