Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to the version containing the fix for the double free issue in cpumf pmu event init()
Description
A double free issue was found in the Linux kernel's PMU event initialization functions, specifically in cpumf pmu event init(), which could lead to a use-after-free error. The performance subsystem common code now always calls event::destroy() to clean up allocated resources during event initialization, resolving the issue. The estimated number of potentially affected devices is not provided.
Recommendations
For Linux kernel versions prior to the version containing the fix, consider updating to a version that includes the fix for the double free issue in cpumf pmu event init() to prevent potential use-after-free errors.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
