CVE-2002-1826

grsecurity 1.9.4 for Linux kernel 2.4.18 allows local users to bypass read-only permissions by using mmap to directly map /dev/mem or /dev/kmem to kernel memory.

CVE-2008-1940

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.
