Pending analysis
Type:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/msm/dp: Free resources after unregistering them<br /> <br /> The DP component&amp;#39;s unbind operation walks through the submodules to<br /> unregister and clean things up. But if the unbind happens because the DP<br /> controller itself is being removed, all the memory for those submodules<br /> has just been freed.<br /> <br /> Change the order of these operations to avoid the many use-after-free<br /> that otherwise happens in this code path.<br /> <br /> Patchwork: https://patchwork.freedesktop.org/patch/542166/
