Linux Kernel Vulnerability in DRM Module Affecting Display Management
CVE-2024-56369
Currently unrated
Summary
A vulnerability exists in the Linux kernel's DRM subsystem where the drm_mode_vrefresh() function inadequately handles potential divide by zero scenarios. Although there are checks to verify if htotal or vtotal are zero, an edge case may still lead to a division by zero error, resulting in potential system instability or crashes. This has prompted the need for a critical update to ensure the robustness of the display management functionalities.
