DRM vblank timer conversion in VKMS

Publication date: 2026-06-08

Last updated on: 2026-06-08

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: drm/vkms: Convert to DRM's vblank timer Replace vkms' vblank timer with the DRM implementation. The DRM code is identical in concept, but differs in implementation. Vblank timers are covered in vblank helpers and initializer macros, so remove the corresponding hrtimer in struct vkms_output. The vblank timer calls vkms' custom timeout code via handle_vblank_timeout in struct drm_crtc_helper_funcs.

Executive Summary

This vulnerability involves the Linux kernel's drm/vkms component, specifically related to the vblank timer implementation. The issue was that vkms used a custom vblank timer, which has now been replaced with the DRM's standard vblank timer implementation. The change removes the custom high-resolution timer in the vkms_output structure and replaces it with the DRM code that handles vblank timers through helpers and initializer macros.
