CWE Code: 119
Vulnerability Type: privilege_escalation
CVSS Score: 7.2
CWE Name:  Improper Restriction of Operations within the Bounds of a Memory Buffer
Summary: 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.
Access Authentication: NONE
Access Complexity: LOW
Access Vector: LOCAL
Impact (C/I/A): COMPLETE/COMPLETE/COMPLETE
