Description
A flaw was found in the Linux kernel's Aeroflex Ethernet driver. During device probing, the driver attempts to attach the physical network interface before its network device operations are assigned. A local user can exploit this condition on systems with network traffic shaping enabled to trigger a NULL pointer dereference, resulting in a kernel crash and a Denial of Service (DoS).
