CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's cpufreq driver for Apple SoCs, specifically in the handling of Operating Performance Points (OPP) tables loaded from firmware. Improper cleanup during failure paths could lead to resource leaks or undefined behavior, potentially impacting system stability and performance. Organizations using Linux on Apple hardware should prioritize this patch to ensure optimal performance and reliability of their systems.
Original NVD Description
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.
