Doc Text:
A flaw was found in the Linux kernel's ASoC fs210x audio codec driver. An incorrect use of the `strscpy` function in `fs210x_effect_scene_info()` can lead to a buffer overflow. This occurs when a string is copied without proper size validation, potentially allowing a local attacker to cause a denial of service or information disclosure.

Description OSIDB Bzimport 2026-07-19 17:08:41 UTC
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)
