CVE-2022-50703

Local service interruption via device-node reference leaks

Published Dec 24, 2025 · Updated Dec 24, 2025

Reference leaks in the Qualcomm SMSM driver in Linux 4.5.0 through 6.0.2 allow local users to interrupt service. In qcom_smsm_probe(), local_node escapes a child-node loop on break and node escapes an available-child loop on goto without matching of_node_put() calls, retaining both references. Low-privileged local access is required; published sources identify availability impact but do not specify whether resource exhaustion produces a hang, crash, or other interruption.
