ID:10366 - Exploit for Use of uninitialized resource in Linux kernel - CVE-2009-2692

Link to public exploit:

Vulnerability description

The vulnerability allows a local user to execute arbitrary code.

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.
