Description

A flaw was found in the Linux kernel's team network driver. When a team interface is configured in broadcast mode and lacks transmittable ports, the driver fails to properly free packet buffers during transmission. A local user can exploit this vulnerability by sending network traffic through the interface, leading to socket memory exhaustion and a Denial of Service (DoS).
