What is CVE-2026-20775?

An unchecked exception within Intel TDX modules operating in Ring 0 may lead to a Denial of Service (DoS) condition. This vulnerability arises when a privileged user maliciously exploits the system, potentially leading to service disruption without the need for special internal knowledge or user interaction. The attack can be executed through local access when specific conditions are met, thereby impacting the system's availability. While confidentiality and integrity remain unaffected, the vulnerability can considerably compromise the system's availability.
