CVE-2026-68254

A flaw was found in the Linux kernel's drm/i915/vrr component. An attacker could provide a specially crafted Extended Display Identification Data (EDID) with a zero minimum vertical refresh rate (min_vfreq). This could lead to a division-by-zero error in the intel_vrr_compute_vmax() function, resulting in a system crash and a Denial of Service (DoS).

This issue affects Intel i915 systems with Variable Refresh Rate (VRR). A malformed EDID with zero min_vfreq can cause division-by-zero in VRR calculations. Systems without Intel graphics or VRR are not affected.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

To mitigate this issue, prevent the i915 module from loading. See https://access.redhat.com/solutions/41278 for instructions.
