Linux Kernel XFRM Array Index Buffer Overflow Vulnerability

Linux kernel is prone to an array index buffer-overflow vulnerability. This issue exists due to insufficient validation of user-supplied data. The vulnerability resides in the XFRM network architecture code.

A successful attack can allow a local attacker to trigger an overflow, which may lead to a denial-of-service condition due to memory corruption. Arbitrary code execution may be possible, but this has not been confirmed.

This issue affects Linux Kernel versions 2.6.x.
