Last week, security researcher Max Kellermann discovered a high severity vulnerability in the Linux kernel, which was assigned the designation CVE-2022-0847. It affects the Linux kernels from 5.8 through any version before 5.16.11, 5.15.25 and 5.10.102, and can be used for local privilege escalation. The vulnerability resides in the pipe tool, which is used for unidirectional communication between processes, so the researcher called it “Dirty Pipe”.
