CVE-2022-36402

System crash via vmwgfx exec-buffer integer overflow

Published Sep 16, 2022 · Updated Sep 17, 2024

Integer overflow in Linux kernel vmwgfx before 5.13.0-52* allows local users to crash the system through a crafted DRM ioctl. The exec-buffer path in drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c performs unchecked integer arithmetic on command data supplied through a DRM device file. Access to /dev/dri/card0 or /dev/dri/renderD128 and permission to issue an ioctl are required; the documented consequence is a system crash.
