CVE-2026-89572

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.
