CVE-2026-89935

Sensor autosuspend prevention via leaked PM reference

Published Sep 16, 2026 · Updated Sep 16, 2026

Resource-management error in Linux 6.10 allows attackers to prevent APDS9306 sensor autosuspend via driver reads that encounter errors. apds9306_read_data() acquires a runtime-PM reference but returns from several later error paths without releasing it. Reachability requires the APDS9306 driver and sensor plus a read failure after acquisition; the disclosed consequence is persistent device activity, not data access or code execution.
