9.1 criticalCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:NCVE-2021-46754
Critical (9.1) in amd. EPSS 0.6% chance of exploitation in the next 30 days.
Insufficient input validation in the ASP (AMD
Secure Processor) bootloader may allow an attacker with a compromised Uapp or
ABL to coerce the bootloader into exposing sensitive information to the SMU
(System Management Unit) resulting in a potential loss of confidentiality and
integrity.
