CVE-2022-50152

Service interruption via device-node reference leak

Published Jun 18, 2025 · Updated May 11, 2026

Resource leak in affected Linux kernel branches starting with 3.5 allows local users to interrupt service via the NXP OHCI probe path. The ohci_hcd_nxp_probe function calls of_parse_phandle(), which increments the ISP1301 device-tree node reference count, but omits the matching of_node_put() after use. The path requires local low-privileged access and compatible NXP hardware described by a device tree; the exact service-interruption mode is not published.
