CVE-2022-50209

Service interruption via unreleased device-tree node reference

Published Jun 18, 2025 · Updated May 11, 2026

Resource leak in affected Linux kernel versions beginning with 4.15 allows local users to interrupt Amlogic Meson MX systems. meson_mx_socinfo_init calls of_find_matching_node but fails to release the incremented device-tree node reference with of_node_put after use. The path is limited to Amlogic Meson MX hardware; public sources do not specify whether resource exhaustion ends in a hang or crash.
