CVE-2024-56369 is a medium severity vulnerability in the Linux kernel's drm_mode_vrefresh() function where a divide-by-zero condition can occur despite checks intended to prevent it. This flaw arises because the function attempts to avoid division by zero by checking if htotal or vtotal are zero, but a division by zero can still happen involving the product of vtotal and htotal. The vulnerability impacts system availability due to potential crashes or denial of service but does not affect confidentiality or integrity.
