Description
A flaw was found in the Linux kernel's OPEN Alliance TC6 (oa_tc6) Ethernet driver. Under heavy or oversubscribed network traffic, missing frame boundaries can cause the driver to append incoming data without verifying that adequate buffer capacity remains. This condition triggers an internal kernel assertion failure, allowing an attacker on the adjacent network to crash the system and cause a Denial of Service (DoS).
