Description
A flaw was found in the Linux kernel's macb Ethernet driver. The napi_consume_skb() function, which is used for freeing network packet buffers (SKBs), was incorrectly called in an interrupt-disabled context. This improper handling of network packet freeing can lead to a kernel warning and system instability, potentially causing a denial of service.
