What is CVE-2026-89572?
CVE-2026-89572 is a memory corruption vulnerability in Linux, published on 11 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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.
