CVE-2026-93113

Power-domain shutdown failure via required clock disabling

Published Sep 17, 2026 · Updated Sep 17, 2026

Clock mismanagement in Linux's SC8280XP camera driver prevents power-domain shutdown when unused clocks are disabled. The camcc-sc8280xp driver registers CAMCC_GDSC_CLK with the Common Clock Framework, which disables it despite its necessity for GDSC transitions. Exposure requires affected SC8280XP hardware and clock/power-domain synchronization; titan_top_gdsc remains on with a kernel warning, while an attacker-controlled trigger or system crash is not documented.
