CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's Direct Rendering Manager (DRM) for Intel graphics, specifically in the handling of variable refresh rate (VRR) where invalid minimum and maximum vertical frequencies (vfreq) could lead to a division by zero error. This flaw could potentially disrupt graphics rendering, impacting system stability and performance. Organizations utilizing affected Linux distributions or F5 products with Intel graphics should prioritize addressing this vulnerability to ensure system reliability and prevent potential exploitation.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: drm/i915/vrr: require valid min/max vfreq for VRR Ensure the EDID provided min/max vfreq are valid. Most scenarios are already covered (by coincidence) through the checks in intel_vrr_is_capable() and intel_vrr_is_in_range(), but be more explicit about it. At worst, a zero min_vfreq could lead to a division by zero in intel_vrr_compute_vmax(). Discovered using AI-assisted static analysis confirmed by Intel Product Security. (cherry picked from commit 1765cf59f517b02f3b0591fe5120930d08bddeb6)
