“Dirty Pipe” Linux Kernel Local Privilege Escalation (LPE) Vulnerability

**CVE-2022-0847 (Dirty Pipe)** is a Linux kernel vulnerability affecting kernels 5.8 and later that allows local attackers with read access to overwrite readonly files and modify data used by privileged processes, enabling privilege escalation and container escape; public PoCs exist and vendors have released patches (e.g., kernels 5.16.11, 5.15.25, 5.10.102), so affected systems should be patched immediately.
