CVE-2023-52645

Service interruption via unsynchronized power-domain transitions

Published Apr 17, 2024 · Updated May 11, 2026

Race condition in the Linux MediaTek power-domain driver allows local users to interrupt service during concurrent power transitions. In mtk-pm-domains.c, probe registers domains with genpd before powering them on, while teardown powers them off before unregistering them. The condition requires affected MediaTek hardware and overlapping genpd and driver transitions, and it interrupts service.
