What is CVE-2026-64041?
CVE-2026-64041 is a high-severity memory corruption vulnerability in Linux kernel, published on 19 Jul 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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)
Weakness: CWE-787
