A divide-by-zero vulnerability in the Linux kernel's AMD display driver (drm/amd/display) was resolved by initializing a dummy pitch value to 1. If dummy values in the function populate_dummy_dml_surface_cfg() were not updated, they could cause a divide-by-zero error in downstream functions like CalculateVMAndRowBytes(). This flaw could lead to a denial of service due to kernel crashes. The issue affects specific Linux kernel versions prior to 6.14.0-1007.7 and 6.14.0-1014.14, as well as certain 3.11 and 3.12 kernel builds. The vulnerability has a medium severity with a CVSS score of 5.5 and does not impact confidentiality or integrity but affects availability. No known exploits are reported in the wild. A fix is available in updated Linux kernel releases.
