Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Linux kernel是美国Linux基金会开源的一款操作系统内核。 Linux kernel 6.18版本存在缓冲区溢出漏洞，该漏洞源于在fs210x_effect_scene_info()函数中使用strscpy时存在缓冲区溢出，当strlen(SRC) >= sizeof(DST)时可能发生溢出。

Vulnerability Title
ASoC: codecs: fs210x: fix possible buffer overflow
Source: CVE Program / CVE List V5
Vulnerability Description
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)
