Background
The thermal/drivers/cpufreq_cooling is a driver in the Linux Kernel that manages the cooling of CPUs based on their frequency. It is responsible for adjusting the cooling devices to prevent overheating. This driver is an essential component of the Linux Kernel and is widely used in various Linux distributions.
Vulnerability Detail
The thermal/drivers/cpufreq_cooling driver in the Linux Kernel versions v5.8 to v5.10.35 is vulnerable to an out-of-bounds (OOB) issue. This vulnerability was introduced in version v5.8 by commit 371a3bc79c11b707d7a1b7a2c938dc3cc042fffb and fixed in version v5.10.36 by commit c24a20912eef00587416628149c438e885eb1304. The OOB issue can potentially be exploited by an attacker to corrupt memory or execute arbitrary code, leading to a denial-of-service (DoS) or privilege escalation.
