Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Linux kernel是美国Linux基金会开源的一个操作系统内核。 Linux kernel 6.2版本存在安全漏洞，该漏洞源于apple_soc_cpufreq_init()从固件添加OPP表后，部分失败路径未将其移除，并且使用了不适用于固件加载OPP表的dev_pm_opp_remove_all_dynamic()清理函数，可能导致OPP表清理不当。

Vulnerability Title
cpufreq: apple-soc: Fix OPP table cleanup
Source: CVE Program / CVE List V5
Vulnerability 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.
