Vulnerability from cvelistv5 – Published: 2024-10-21 18:01 – Updated: 2026-05-11 20:41

Title

drm/amd/display: Initialize denominators' default to 1

Summary

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Initialize denominators' default to 1 [WHAT & HOW] Variables used as denominators and maybe not assigned to other values, should not be 0. Change their default to 1 so they are never 0. This fixes 10 DIVIDE_BY_ZERO issues reported by Coverity.
