CVE-2022-50574

Kernel resource leak via unreleased node references

Published Oct 22, 2025 · Updated Oct 22, 2025

Reference leakage in Linux 4.12 and later OMAP DSS code allows attackers to consume kernel resources during port setup or teardown. dss_init_ports() and __dss_uninit_ports() fail to call of_node_put() for references returned by of_graph_get_port_by_id() on failure or after use. Reachability requires the OMAP DSS device-tree port path; the published record documents neither an unprivileged trigger nor a demonstrated crash.
