Description

A flaw was found in the Linux kernel's IBM EMAC network driver. During module removal, the driver unconditionally attempts to disable network polling routines even if they were never enabled or were already stopped. This improper state handling causes the kernel to enter an infinite loop, resulting in a system hang and a Denial of Service (DoS).
