Background
The mlxsw: thermal vulnerability affects the Kernel package in the Linux ecosystem. The Kernel package is a critical component of the Linux operating system, responsible for managing the system's core functions and providing an interface between hardware and software. The mlxsw: thermal module within the Kernel package is specifically responsible for thermal management of Mellanox Switches (mlxsw). This vulnerability arises from out-of-bounds memory accesses within the mlxsw: thermal module, which can lead to various security issues.
Vulnerability Detail
The mlxsw: thermal vulnerability is caused by out-of-bounds memory accesses. This means that the module accesses memory outside the bounds of what is allocated, potentially leading to memory corruption, crashes, or even remote code execution. An attacker could exploit this vulnerability to gain unauthorized access, escalate privileges, or cause denial of service. The vulnerability was introduced in version v4.10 of the Linux Kernel and is fixed in version v5.10.75.
