Note that this only affects the combination of bubblewrap in setuid mode (which is typically used when unprivileged user namespaces are not supported) and the support of unprivileged user namespaces. Known to be affected ... • https://github.com/containers/bubblewrap/commit/1f7e2ad948c051054b683461885a0215f1806240 • CWE-269: Improper Privilege Management CWE-648: Incorrect Use of Privileged APIs •
