CVE-2025-71315
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.
Affected versions
Linux kernel versions
4.19
and later are affected. Fixed in
6.18.34,
6.19
and their respective stable series.
