VMware kernel NULL pointer dereference vulnerability

oval:org.mitre.oval:def:8657

The Linux kernel 2.6.0 through 2.6.30.4 and 2.4.4 through 2.4.37.4 does not initialize all function pointers for socket operations in proto_ops structures which allows local users to trigger a NULL pointer dereference and gain privileges by using mmap to map page zero placing arbitrary code on this page and then invoking an unavailable operation as demonstrated by the sendpage operation (sock_sendpage function) on a PF_PPPOX socket.
