Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/client: Fix memory leak in drm_client_target_cloned
dmt_mode is allocated and never freed in this function.
It was found with the ast driver, but most drivers using generic fbdev
setup are probably affected.
This fixes the following kmemleak report:
