CVE-2026-89572

Unspecified impact via stale firmware OPP tables

Published Sep 11, 2026 · Updated Sep 11, 2026

Resource-management error in the apple-soc cpufreq driver in Linux 6.2 allows attackers to cause unspecified impact via unspecified vectors. apple_soc_cpufreq_init() leaves firmware-loaded OPP tables registered on some failure paths and uses a dynamic-OPP removal helper that does not match firmware tables. Exposure is limited to Apple SoC systems using this driver when initialization fails or the driver exits; the upstream record does not identify a resulting security consequence.
