In the Linux kernel, the following vulnerability has been resolved: drm/msm/dp: Free resources after unregistering them The DP component's unbind operation walks through the submodules to unregister and clean things up. But if the unbind happens because the DP controller itself is being removed, all the memory for those submodules has just been freed. Change the order of these operations to avoid the many use-after-free that otherwise happens in this code path. Patchwork: https://patchwork.freedesktop.org/patch/542166/
