Discussion

Linux Kernel Fib_Semantics.C Out Of Bounds Access Vulnerability

The Linux kernel is prone to an out-of-bounds-access vulnerability. This issue occurs because the semantics for IPv4 Forwarding Information Base fail to adequately bounds-check user-supplied data before accessing an array.

An attacker can exploit this issue to cause denial-of-service conditions. Arbitrary code execution may also be possible, but this has not been confirmed.

Versions prior to 2.6.21-rc6 are vulnerable.
