CVE-2026-80701Hinoki check available

Kernel crash via unchecked MOB cursor dimensions

Published Aug 28, 2026 · Updated Aug 28, 2026

NULL pointer dereference in Linux 6.16 vmwgfx allows local users with DRM master access to crash the kernel via an oversized cursor. vmw_cursor_plane_prepare_fb discards vmw_cursor_mob_get failure, leaving the MOB pointer NULL before vmw_cursor_update_mob maps it. Exploitation requires DRM master control and a VMware virtual GPU using MOB cursors; the resulting kernel oops interrupts the guest system.
