Background
The Linux Kernel is the core component of the Linux operating system, responsible for managing system resources and providing an interface for applications to interact with the hardware. The netlabel subsystem in the Linux Kernel is used for network labeling, allowing administrators to assign security labels to network packets. This helps in enforcing security policies based on these labels. However, a vulnerability has been discovered in the netlabel subsystem that can lead to out-of-bounds memory accesses.
Vulnerability Detail
The netlabel vulnerability in the Linux Kernel allows an attacker to perform out-of-bounds memory accesses. This can potentially lead to memory corruption, crashes, or even remote code execution. The vulnerability was introduced in version 2.6.19 of the Linux Kernel and was fixed in version 4.14.106. The specific commit that fixed the vulnerability is fcfe700acdc1c72eab231300e82b962bac2b2b2c. The impact and attack plausibility of this vulnerability have not been proven yet.
