Background
The x86/pm package is a component of the Linux Kernel, which is responsible for managing power management features on x86-based systems. It includes functionality for handling MSR (Model Specific Register) contexts. MSR contexts are used to save and restore the state of MSR registers during system sleep and resume operations. This vulnerability in the package leads to false positive kmemleak reports in the msr_build_context() function.
Vulnerability Detail
The vulnerability arises from a false positive kmemleak report in the msr_build_context() function of the x86/pm package. The kmemleak feature in the Linux Kernel is used to detect and report memory leaks. However, in this case, the msr_build_context() function triggers a false positive report, indicating a memory leak that does not actually exist. This can lead to unnecessary investigation and potential wasted resources. The issue was introduced in version v4.5 of the Linux Kernel and has been fixed in version v4.19.247.
How To Fix
