Doc Text:
A vulnerability was found in the Linux kernel where the Lantiq Ethernet driver could cause a double-free error due to improper handling of network packet descriptors. This issue occurs because the counter tracking released descriptors are not incremented correctly, leading to the same network packet buffer being released multiple times. This flaw can result in memory corruption, causing unexpected behavior, system crashes, or even creating opportunities for attackers to exploit the system.
