Vulnerability from github – Published: 2026-07-19 18:31 – Updated: 2026-07-20 15:31

Details

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)

Severity

7.8 (High)
