Background

The CDC-NCM package is a component of the Linux Kernel ecosystem. It is responsible for performing sanity checking in the kernel. This process ensures that the system is in a stable and secure state. However, a vulnerability has been discovered in the CDC-NCM package that allows for potential overflow during the sanity checking process.

Vulnerability Detail

The vulnerability in the CDC-NCM package arises from a lack of proper bounds checking. This can lead to an overflow condition, potentially allowing an attacker to execute arbitrary code or cause a denial of service. The impact and attack plausibility of this vulnerability have not been proven yet. The vulnerability has been fixed in Linux Kernel version v5.16.12 by commit 7b737e47b87589031f0d4657f6d7b0b770474925.
