Description
A flaw was found in the Linux kernel's Marvell mv643xx Ethernet driver. This flaw can result in a Denial of Service (DoS) by causing the system to crash during device initialization. The issue occurs because the driver attempts to attach the physical network interface before assigning its internal operations table. When network traffic shaping features are enabled, this improper ordering triggers a null pointer dereference that halts the kernel during device probing.
