## Overview

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

cpufreq: apple-soc: Fix OPP table cleanup

apple_soc_cpufreq_init() adds OPP tables from firmware, but
some failure paths do not remove them. The driver also uses
dev_pm_opp_remove_all_dynamic(), which is not the right cleanup
helper for OPP tables loaded from firmware.

Use the cpumask OPP helper after the policy CPU mask has been
populated. Pair it with the matching cpumask remove helper on
failure paths and in apple_soc_cpufreq_exit(). This also removes
the separate dev_pm_opp_set_sharing_cpus() call, as the cpumask
helper loads the DT OPP tables for all CPUs in the policy.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
