Official description

In the Linux kernel, the following vulnerability has been resolved: drm/client: Do not destroy NULL modes 'modes' in drm_client_modeset_probe may fail to kcalloc. If this occurs, we jump to 'out', calling modes_destroy on it, which dereferences it. This may result in a NULL pointer dereference in the error case. Prevent that.
