What CVE-2026-46331 Is and Why Your Antivirus Cannot See It
CVE-2026-46331 is a critical vulnerability (CVSS 9.1) in the Linux kernel eBPF subsystem — versions 5.15 to 6.8 — that allows an attacker to load malicious code directly into kernel memory without writing any file to disk. Traditional antivirus solutions cannot detect it because they scan the filesystem: a threat that never touches disk is, from their perspective, completely invisible. Your Linux servers may be actively compromised right now with no alert ever generated.
