Описание
In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: lantiq_etop: fix double free in detach
The number of the currently released descriptor is never incremented
which results in the same skb being released multiple times.
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.
Отчет
This vulnerability is rated as IMPORTANT because it directly affects system stability and could be leveraged for attacks resulting in high confidentiality, integrity, and availability impacts.
Меры по смягчению последствий
It is recommended to update to the latest stable kernel version to address this vulnerability.
