NVD Description

Note: Versions mentioned in the description apply only to the upstream python3-perf6.12-debuginfo package and not the python3-perf6.12-debuginfo package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2023 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

ACPI: processor: Unregister cpufreq notifier on init failure

acpi_processor_driver_init() registers the cpufreq policy notifier before registering the ACPI processor driver and setting up CPU hotplug state.

If driver_register() or cpuhp_setup_state() fails, the error path only unregisters the ACPI processor driver and the idle driver. The cpufreq notifier remains registered even though initialization failed.

Mirror the module exit path on the init failure path and unregister the cpufreq notifier when it has been registered.
