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)
