Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
drm/msm: Fix bootup splat with separate_gpu_drm modparam
The drm_gem_for_each_gpuvm_bo() call from lookup_vma() accesses drm_gem_obj.gpuva.list, which is not initialized when the drm driver does not support DRIVER_GEM_GPUVA feature. Enable it for msm_kms drm driver to fix the splat seen when msm.separate_gpu_drm=1 modparam is set:
