The RBAC functionality in grsecurity before 2.1.11-2.6.24.5 and 2.1.11-2.4.36.2 does not enforce user_transition_deny and user_transition_allow rules for the (1) sys_setfsuid and (2) sys_setfsgid calls, which allows local users to bypass restrictions for those calls.

Security readout for executives and security teams

CVE-2008-1940 is a grsecurity RBAC bypass affecting older grsecurity releases. A local user could bypass specific user transition restrictions for filesystem UID/GID related system calls. This is mainly relevant to legacy Linux systems that still depend on grsecurity RBAC for local privilege boundary enforcement. Exposure appears limited to systems running affected legacy grsecurity RBAC versions. The source bundle identifies no broader product CPEs. Practical risk depends on whether local users exist and whether RBAC policy relies on user transition controls. Treat this as a legacy exposure review, not an internet-wide emergency. Prioritize if grsecurity RBAC protects shared shell hosts, regulated workloads, or systems with untrusted local users. Otherwise, track through normal vulnerability hygiene. Mitigation focus: Identify systems still running grsecurity RBAC on affected legacy versions.; Upgrade to grsecurity 2.1.11-2.6.24.5, 2.1.11-2.4.36.2, or later where applicable.; Check current vendor guidance if maintaining a legacy grsecurity deployment..
