# CVE-2026-80740

> 3.1 LOW

## Beschreibung

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.

## Patch verfügbar (OSV)

- Kernel ≥ 6.18.46
- Kernel ≥ 7.1.10
