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 that provides core functionality and manages system resources. The mlxsw: thermal module is responsible for thermal management in Mellanox Switches (mlxsw). This vulnerability specifically involves out-of-bounds memory accesses, which can lead to various security issues.
