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.

Unspecified vulnerability in the expand_stack function in grsecurity PaX allows local users to gain privileges via unspecified vectors. NOTE: the grsecurity developer has disputed this issue, stating that "the function they claim the vulnerability to be in is a trivial function, which can, and has been, easily checked for any supposed vulnerabilities." The developer also cites a past disclosure that was not proven. As of 20070120, the original researcher has released demonstration code
