CVE-2008-1940 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.32% chance of exploitation in the next 30 days.
