cpufreq: apple-soc: Fix OPP table cleanup

Published Sep 11, 2026 CVSS 3.1 · 2.3 Low EPSS < 1% KEV · Not listed

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.

Analysis

Technical impact

The apple‑soc cpufreq driverP) tables that are loaded from firmware when driver initialization fails, leading to stale kernel memory entries and resource exhaustion. This flaw does not grant direct confidentiality or integrity violations; it merely depletes system resources until the driver is reloaded or the machine is rebooted.

Affected Systems

All Linux kernel releases that contain the unpatched apple‑soc cpufreq driver are subject to this issue. Any kernel version prior to the patch remains at risk until a newer kernel incorporating the fix is installed.

Risk and Exploitability

The CVSS score of 2.3 indicates low severity and the EPSS score of <1% suggests a very low likelihood of exploitation. The vulnerability requires local kernel interaction during driver initialization; no remote attack vector or privilege escalation is documented. The attack vector is inferred driver load and cleanup paths. Since the issue is not listed in the CISA KEV catalog, the overall risk is that a malicious local user or process could deplete kernel resources by triggering repeated failed initialization or unloads of the driver.
