6.2
MEDIUM · CVSS 2.0 · EPSS 3.3% (pctl 88)
Patch early
A public exploit exists.
Description
The capabilities implementation in the Linux kernel before 3.14.8 does not properly consider that namespaces are inapplicable to inodes, which allows local users to bypass intended chmod restrictions by first creating a user namespace, as demonstrated by setting the setgid bit on a file with group ownership of root.
