CVE-2023-2640 and CVE-2023-32629 were found in the OverlayFS module in Ubuntu, which is a widely used Linux filesystem that became highly popular with the rise of containers as its features enable the deployment of dynamic filesystems based on pre-built images. OverlayFS serves as an attractive attack surface as it has a history of numerous logical vulnerabilities that were easy to exploit. This makes the new discovered vulnerabilities especially risky given the exploits for the past OverlayFS vulnerabilities work out of the box without any changes.
The two vulnerabilities are exclusive to Ubuntu because Ubuntu introduced several changes to the OverlayFS module in 2018. These modifications did not pose any risks at the time. In 2020, a security vulnerability was discovered and patched in
