If drm_gem_handle_create() fails in vkms_gem_create(), then the vkms_gem_object is freed twice: once when the reference is dropped by drm_gem_object_put_unlocked(), and again by the extra calls to drm_gem_object_release() and kfree().
Fix it by skipping the second release and free.
This bug was originally found in the vgem driver by syzkaller using fault injection, but I noticed it's also present in the vkms driver.

Hi,
Thanks for your patch! :)
The patch looks good for me. I also tested it under the IGT tests on my local VM and everything was fine.

Hi Rodrigo,

Hi Dmitry,
IGT is a test suite focused on DRM drivers.
You can clone the project using the link below:
https://gitlab.freedesktop.org/drm/igt-gpu-tools.git
In the README, you will find the software dependencies. After you install all the required package, just use:
mkdir build && meson build && cd build && ninja
Finally, if you want to test VKMS, I recommend you to do it inside a VM.
Best Regards Rodrigo Siqueira
