Detailsinfo

A vulnerability has been found in Linux Kernel 2.6.16.9 (Operating System) and classified as critical. This vulnerability affects the function inet_diag_bc_audit. The manipulation with an unknown input leads to a resource management vulnerability. The CWE definition for the vulnerability is CWE-399. As an impact it is known to affect availability. CVE summarizes:

The inet_diag_bc_audit function in net/ipv4/inet_diag.c in the Linux kernel before 2.6.39.3 does not properly audit INET_DIAG bytecode, which allows local users to cause a denial of service (kernel infinite loop) via crafted INET_DIAG_REQ_BYTECODE instructions in a netlink message, as demonstrated by an INET_DIAG_BC_JMP instruction with a zero yes value, a different vulnerability than CVE-2010-3880.

The issue has been introduced in 03/20/2006. The weakness was released 08/29/2011 by Dan Rosenberg as Bug 714536 as not defined bug report (Bugzilla).
