CVE-2026-80740

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.
