The Dirty Pipe Vulnerability — The Dirty Pipe Vulnerability documentation
This is the story of CVE-2022-0847, a vulnerability in the Linux kernel since 5.8 which allows overwriting data in arbitrary read-only files. This leads to privilege escalation because unprivileged processes can inject code into root processes. It is similar to CVE-2016-5195 “Dirty Cow” but is easier to exploit. The vulnerability was fixed in Linux 5.16.11, 5.15.25 and 5.10.102.

Reptile Malware Targeting Linux Systems
Reptile is an open-source kernel module rootkit that targets Linux systems and is publicly available on GitHub. [1] Rootkits are malware that possess the capability to conceal themselves or other malware. They primarily target files, processes, and network communications for their concealment. Reptile’s concealment capabilities include not only its own kernel module but also files, directories, file contents, processes, and network traffic. Unlike other rootkit malware that typically only provide concealment capabilities, Reptile goes a step further by offering a reverse...
