## Overview

In the Linux kernel, the following vulnerability has been resolved:

fbmon: prevent division by zero in fb_videomode_from_videomode()

The expression htotal * vtotal can have a zero value on
overflow. It is necessary to prevent division by zero like in
fb_var_to_videomode().

Found by Linux Verification Center (linuxtesting.org) with Svace.

## Affected

- `linux_kernel < 4.19.312`
- `linux_kernel >= 4.20, < 5.4.274`
- `linux_kernel >= 5.5, < 5.10.215`
- `linux_kernel >= 5.11, < 5.15.155`
- `linux_kernel >= 5.16, < 6.1.86`
- `linux_kernel >= 6.2, < 6.6.27`
- `linux_kernel >= 6.7, < 6.8.6`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.8.6`
