Resolved Date: Feb 10, 2015
Found In Version: 7.0
Fix Version:
Severity: Standard
Applicable for: Wind River Linux 7
Component/s: Kernel


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.
