CVE-2025-71315 Linux CVE debrief

A vulnerability in the Linux kernel has been resolved. The vulnerability was related to the drm/vkms module, which has been converted to use DRM's vblank timer. This change replaces vkms' vblank timer with the DRM implementation, which is identical in concept but differs in implementation. The vblank timer calls vkms' custom timeout code via handle_vblank_timeout in struct drm_crtc_helper_funcs.
