The Dirty Pipe vulnerability is a significant security issue in Linux-based systems that allows underprivileged processes to write arbitrary data to readable files, leading to privilege escalation. The vulnerability was introduced in the Linux kernel through a code refactoring and was first publicly disclosed by Max Kellermann on March 7, 2022. It has been fixed for all currently maintained releases of Linux, but many systems may remain vulnerable due to their older kernel versions. The vulnerability can be exploited to break out from unprivileged containers, including those used by Docker and Kubernetes, and can be detected using tools like Datadog Cloud Workload Security. To remediate the vulnerability, users need to ensure their Linux systems are running a kernel version of 5.16.11 or more recent, and major Linux distributions have released dedicated security bulletins to help mitigate the issue.
