| Vector | AV:L/AC:L/Au:S/C:N/I:C/A:C |
Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
The
clone private mnt() function did not properly verify that the caller has CAP SYS ADMIN privileges within the correct user namespace. This could potentially allow exposure of hidden mounts that cannot be undone, particularly in scenarios involving MNT LOCKED mounts or lacking administrative rights in the user namespace where the mount belongs. The existing checks within the mount API were found to be insufficient in covering this specific scenario.Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
