1) Improper locking (CVE-ID: CVE-2005-2456)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

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.
