The version of Docker Desktop for Windows is prior to 4.6.0. It is therefore affected by CVE-2022-0847, AKA ‘DirtyPipe’, an issue that could enable attackers to modify files in container images on the host, from inside a container.

A flaw was found in the way the ‘flags’ member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system. (CVE-2022-0847)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
