Summary

In the Linux kernel, the apple-soc cpufreq driver did not remove OPP tables on some failure paths and used the wrong helper dev_pm_opp_remove_all_dynamic() for cleaning up firmware-loaded OPP tables. The fix uses the cpumask OPP helper after the policy CPU mask is populated, paired with the matching remove helper on failure paths and in apple_soc_cpufreq_exit().

Risk Assessment

Improper OPP table cleanup can lead to resource leaks or CPU frequency management errors on Apple Silicon devices, potentially causing system instability.

Recommendation

Update the Linux kernel to a version containing the OPP table cleanup fix in the apple-soc cpufreq driver.

Original NVD description (English source)

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.
