CVE-2026-68254

The Linux kernel component drm/i915/vrr was updated to enforce that EDID-provided min_vfreq and max_vfreq are valid for VRR. The root cause was inadequate validation of VRR frequencies, with a potential division-by-zero in intel_vrr_compute_vmax if min_vfreq was zero. The fix explicitly validates...
