• CVE-2022-23821 Unrated Improper access control in System Management Mode (SMM) may allow an attacker to write to SPI ROM potentially leading to arbitrary code execution. 1.0%
• CVE-2023-20521 Low 3.3 TOCTOU in the ASP Bootloader may allow an attacker with physical access to tamper with SPI ROM records after memory content verification, potentially leading to loss of confidentiality or a denial of 0.3%
• CVE-2023-20555 Unrated Insufficient input validation in CpmDisplayFeatureSmm may allow an attacker to corrupt SMM memory by overwriting an arbitrary bit in an attacker-controlled pointer potentially leading to arbitrary cod 0.3%
• CVE-2021-46794 High 7.5 Insufficient bounds checking in ASP (AMD Secure Processor) may allow for an out of bounds read in SMI (System Management Interface) mailbox checksum calculation triggering a data abort, resulting in a 0.6%
• CVE-2021-46759 Medium 6.1 Improper syscall input validation in AMD TEE (Trusted Execution Environment) may allow an attacker with physical access and control of a Uapp that runs under the bootloader to reveal the contents of t 0.3%
• CVE-2021-46756 Critical 9.1 Insufficient validation of inputs in SVC_MAP_USER_STACK in the ASP (AMD Secure Processor) bootloader may allow an attacker with a malicious Uapp or ABL to send malformed or invalid syscall to the boot 0.6%
• CVE-2021-46754 Unrated 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 0.6%
• CVE-2021-46753 Critical 9.1 Failure to validate the length fields of the ASP (AMD Secure Processor) sensor fusion hub headers may allow an attacker with a malicious Uapp or ABL to map the ASP sensor fusion hub region and overwri 0.6%
• CVE-2021-46749 High 7.5 Insufficient bounds checking in ASP (AMD Secure Processor) may allow for an out of bounds read in SMI (System Management Interface) mailbox checksum calculation triggering a data abort, resulting in a 0.6%
• CVE-2021-26406 High 7.5 Insufficient validation in parsing Owner's Certificate Authority (OCA) certificates in SEV (AMD Secure Encrypted Virtualization) and SEV-ES user application can lead to a host crash potentially result 0.4%
• CVE-2021-26371 Medium 5.5 A compromised or malicious ABL or UApp could send a SHA256 system call to the bootloader, which may result in exposure of ASP memory to userspace, potentially leading to information disclosure. 0.2%
• CVE-2021-26365 High 8.2 Certain size values in firmware binary headers could trigger out of bounds reads during signature validation, leading to denial of service or potentially limited leakage of information about out-of-bo 0.6%
• CVE-2021-26354 Medium 5.5 Insufficient bounds checking in ASP may allow an attacker to issue a system call from a compromised ABL which may cause arbitrary memory values to be initialized to zero, potentially leading to a loss 0.2%
