CVE-2022-0847 Dirty Pipe: Overwrite Files, Get Root
CVE-2022-0847, named Dirty Pipe, is a Linux kernel vulnerability allowing any unprivileged local user to write to arbitrary read-only files and achieve root privilege escalation. Unlike the 2016 Dirty Cow vulnerability it resembles, Dirty Pipe requires no race condition, it is deterministic and reliable. Affects Linux kernels 5.8 through 5.16.10 and was quickly weaponized for container escapes and Android rooting.
