Background
The x86/pm package is a component of the Linux Kernel that handles power management for x86 architecture. It provides functionality for managing power states, CPU frequency scaling, and other related tasks. The package is an integral part of the Linux Kernel and is widely used in various Linux distributions. However, a vulnerability has been discovered in the package that leads to false positive kmemleak reports in the msr_build_context() function.
Vulnerability Detail
The vulnerability in x86/pm package arises from a false positive kmemleak report in the msr_build_context() function. This function is responsible for building the context for accessing Model-Specific Registers (MSRs) on x86 processors. Due to a coding error, the function incorrectly triggers kmemleak reports, which are used to detect memory leaks in the kernel. This false positive report can lead to confusion and unnecessary investigation of non-existent memory leaks. While the impact of this vulnerability is relatively low, it can cause unnecessary resource consumption and potentially divert attention from genuine memory leak issues.
How To Fix
