kernel: privilege escalation
| Package(s): | kernel |
CVE #(s): | CVE-2009-2692
|
| Created: | August 18, 2009 |
Updated: | October 5, 2009 |
| Description: |
From the Mandriva advisory: 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 on a PF_PPPOX
socket. |
