You might have heard about a new Linux vulnerability that was released last week, CVE-2022-0847, aka “Dirty Pipe”. This vulnerability overwrites supposedly read-only files in the Linux kernel host, which could enable attackers to modify files inside the host images from the container instance.
If you use Docker Engine natively, we recommend you should update your Linux OS to a version that has patched the vulnerability, e.g. Linux 5.16.11, 5.15.25, and 5.10.102.
For those of you using Docker Desktop, we recently released a patch of our own for Mac and for Windows.
- Docker Desktop for Mac – update to the latest release
- Docker Desktop for Windows – update to the latest release
- If you have enabled WSL2 – you need to update the kernel from Microsoft as well.
