Background
The thermal/drivers/cpufreq_cooling module is a part of the Linux Kernel, which is responsible for managing the thermal cooling devices and their frequency scaling. It provides a framework for controlling the CPU frequency based on the thermal conditions. The cpufreq_cooling driver specifically handles the cooling devices associated with the CPU frequency scaling. This vulnerability affects versions of the Linux Kernel from v5.8 to v5.12.2.
Vulnerability Detail
The vulnerability identified in thermal/drivers/cpufreq_cooling is an out-of-bounds (OOB) issue. It occurs due to improper handling of slab allocations, leading to potential memory corruption. An attacker could exploit this vulnerability to execute arbitrary code or cause a denial-of-service (DoS) condition. The impact and attack plausibility of this vulnerability have not been proven yet.
