Description

Array index overflow in the xfrm_sk_policy_insert function in xfrm_user.c in Linux kernel 2.6 allows local users to cause a denial of service (oops or deadlock) and possibly execute arbitrary code via a p-dir value that is larger than XFRM_POLICY_OUT which is used as an index in the sock-sk_policy array.
