GHSA-86G9-4XM6-2VW3

Vulnerability from github – Published: 2022-05-17 03:10 – Updated: 2025-04-12 12:42

Details

The Linux kernel through 3.17.4 does not properly restrict dropping of supplemental group memberships in certain namespace scenarios, which allows local users to bypass intended file permissions by leveraging a POSIX ACL containing an entry for the group category that is more restrictive than the entry for the other category, aka a "negative groups" issue, related to kernel/groups.c, kernel/uid16.c, and kernel/user_namespace.c.
