CVE-2022-50188

CVE-2022-50188 is a Linux kernel vulnerability where a refcount leak in drm/meson was fixed. The issue arose because of how of_find_device_by_node() held a reference, with missing put_device() in the error path, leading to a refcount leak. The fix patches the kernel (meson_encoder_hdmi_init) to r...
