CVE-2022-50038

Service interruption via leaked device-tree references

Published Jun 18, 2025 · Updated May 11, 2026

Resource leaks in the Meson DRM driver in affected Linux kernels starting with 4.10 allow local users to interrupt service. meson_vpu_has_available_connectors() exits connector iteration without releasing an endpoint reference and leaves a remote-port reference unreleased. The path is limited to systems using the Meson graphics driver; published evidence establishes availability impact but does not specify the failure mode.
