CVE-2022-0847: Dirty Pipe (Linux Kernel)
What is Dirty Pipe?
A vulnerability in the Linux kernel that allows overwriting data in arbitrary read-only files. By exploiting the pipe buffer mechanism, unprivileged users can inject data into cached pages of files they can read, including SUID root binaries.
Impact & Exploitation
Enables local privilege escalation to root on any Linux system running kernel 5.8+. Similar impact to Dirty COW but easier to exploit. Affects millions of Linux servers and Android devices.
