25
FAUCET Score

CVE-2021-26335 describes a critical vulnerability in the AMD Secure Processor (ASP) boot loader, where improper input and range checking allows an attacker to manipulate values before signature validation, potentially leading to arbitrary code execution. With a CVSS score of 7.8 (High), this local vulnerability requires low privileges and low attack complexity, posing a significant risk of high impact to confidentiality, integrity, and availability. Despite its severity, there is currently no public exploit code available (Metasploit, Nuclei, ExploitDB), nor is it listed in CISA's KEV catalog. Community discussion and media coverage for this CVE are also minimal.
