CVE-2022-50641

Resource retention via device-node refcount leak

Published Dec 9, 2025 · Updated May 11, 2026

Reference-count leakage in the Linux kernel OMAP SSI probe allows attackers to retain device-node references through failed probe paths. The ssi_probe child-node loop returns or breaks without calling of_node_put(), leaving the current device-tree node referenced. Exposure requires the OMAP SSI driver and a relevant probe path; published sources establish neither an attacker-controlled trigger nor a demonstrated service crash.
