CVE		CVE-2009-2692
Status		UNKNOWN
Description		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.
Severity		High
CVSS score		7,2
CVSS vector		(AV:L/AC:L/Au:N/C:C/I:C/A:C)
Phase		ASSIGNED (21.08.2010)
