Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.17.0-rc4-assorted-fix-00005-g0e9bb53a2282-dirty
Description
The Linux kernel contains an issue where the
drm gem for each gpuvm bo() call from lookup vma() accesses drm gem obj.gpuva.list, which is not initialized when the DRIVER GEM GPUVA feature is not supported by the DRM driver. This can lead to a system crash, specifically a kernel oops, when the msm.separate gpu drm=1 module parameter is set. The issue occurs during the boot process.Recommendations
Update to a newer version of the Linux kernel that contains a fix for this vulnerability.
