CyberRota Analysis

AI-Generated

The vulnerability affects the Linux kernel's Direct Rendering Manager (DRM) subsystem, specifically in the handling of display scaling where excessively large scale values can lead to zero rows or columns, resulting in an infinite loop during logging operations. This can cause system instability and potential denial of service due to resource exhaustion. Linux system administrators and developers utilizing the DRM subsystem should prioritize addressing this issue to ensure system reliability and prevent potential disruptions.

Original NVD Description

In the Linux kernel, the following vulnerability has been resolved: drm/log: Fix infinite loop when scale is too large for display When scale is large enough that scaled_font exceeds the display dimensions, rows or columns become 0. A columns value of 0 causes an infinite loop in drm_log_draw_kmsg_record() because the loop never decrements len. Check for zero rows/columns in drm_log_setup_modeset() and return an error, cleaning up the already allocated buffer to avoid a leak.
