In the Linux kernel, the following vulnerability has been resolved:
drm/v3d: Validate passed in drm syncobj handles in the performance extension
If userspace provides an unknown or invalid handle anywhere in the handle array the rest of the driver will not handle that well.
Fix it by checking handle was looked up successfully or otherwise fail the extension by jumping into the existing unwind.
