AI-suggested
A fix is available in updated Linux kernel versions including those released after 6.14.0-1007.7 and 6.14.0-1014.14, as well as patched versions of 3.11.x through 3.13.x kernels. Users and administrators should apply these official kernel updates to remediate the vulnerability. No additional mitigation steps are indicated by the vendor advisory.
Description
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.
