In the Linux kernel, the following vulnerability has been resolved:
drm/rockchip: dw_hdmi: cleanup drm encoder during unbind
This fixes a use-after-free crash during rmmod.
The DRM encoder is embedded inside the larger rockchip_hdmi,
which is allocated with the component. The component memory
gets freed before the main drm device is destroyed. Fix it
by running encoder cleanup before tearing down its container.
