Go to dashboardIn the Linux kernel's MediaTek DRM driver, mtk_drm_bind() takes a reference to the disp-mutex device and returns early on non-master devices without releasing it. The fix drops that reference before the early return.

Systems running a Linux kernel with the MediaTek DRM driver on MediaTek SoC hardware with multiple display devices, where a non-master mmsys device binds. Standard x86 servers and most cloud VMs do not load this driver, so they can skip it. The sources do not describe the exact trigger conditions beyond this code path.

In the Linux kernel, the following vulnerability has been resolved:
drm/mediatek: Fix pdev reference leak in mtk_drm_bind()
When the device is not the mmsys master, mtk_drm_bind() returns early after taking a reference on the disp-mutex device via of_find_device_by_node(), without ever dropping it: mtk_drm_unbind() only puts mutex_dev for the master. Drop the reference before returning from the non-master path.
