CVSS 2.0 ([email protected]): 7.2 HIGH — AV:L/AC:L/Au:N/C:C/I:C/A:C
Weaknesses: CWE-908

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.

Affected configurations

• linux linux kernel (>= 2.4.4 < 2.4.37.5) • linux linux kernel (>= 2.6.0 < 2.6.30.5) • debian debian linux 4.0 • suse linux enterprise real time 10 • redhat enterprise linux desktop 4.0 • redhat enterprise linux desktop 5.0 • redhat enterprise linux eus 4.8 • redhat enterprise linux eus 5.3 • redhat enterprise linux server 4.0 • redhat enterprise linux server 5.0 • redhat enterprise linux server aus 5.3 • redhat enterprise linux workstation 4.0 • redhat enterprise linux workstation 5.0
