## Overview

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

ASoC: codecs: fs210x: fix possible buffer overflow

In fs210x_effect_scene_info(), a string was copied like this:

    strscpy(DST, SRC, strlen(SRC) + 1);

A buffer overflow would happen if strlen(SRC) >= sizeof(DST).
Actually, strscpy() must be used this way:

    strscpy(DST, SRC, sizeof(DST));
    strscpy(DST, SRC); // defaults to sizeof(DST)

## Affected

- `linux_kernel >= 6.18, < 6.18.34`
- `linux_kernel >= 6.19, < 7.0.11`
- `linux_kernel = 7.1`

## Remediation

Upgrade past the affected range:

- `linux_kernel 7.0.11`
