CVE-2025-40152

Boot-time kernel crash via uninitialized GPUVA list

Published Nov 12, 2025 · Updated May 11, 2026

Denial of service in the Linux kernel 6.17 allows attackers to crash Qualcomm MSM graphics systems during driver initialization. The lookup_vma() path iterates drm_gem_obj.gpuva.list even though msm_kms leaves that list uninitialized without DRIVER_GEM_GPUVA. Reachability requires the msm.separate_gpu_drm=1 module parameter and affected Qualcomm graphics hardware; the resulting kernel oops interrupts system startup.
