CVE-2023-2640
Needs a user account on the system (even unprivledged accounts) via overlayfs
Overlayfs allows one, usually read-write, directory tree to be overlaid onto another, read-only directory tree. All modifications go to the upper, writable layer. This type of mechanism is most often used for live CDs but there is a wide variety of other uses.

The Wiz announcement didn’t really go into specifics, so not sure other than normal user auditing.
Is this an Ubuntu specialty, or other distros are also affected?
