CVE-2022-49382

Service interrupt via GRF node reference leak

Published Feb 26, 2025 · Updated May 11, 2026

Device-node reference leakage in the Rockchip GRF driver in Linux 4.11 through 5.18.3 allows local users to cause a service interrupt. rockchip_grf_init calls of_find_matching_node_and_match, which increments the matched node's reference count, but omits of_node_put after consuming the node. Exposure requires the affected Rockchip GRF initialization path and a matching Device Tree node; public sources identify no user-controlled trigger.
