CVE-2021-46759
https://notcve.org/view.php?id=CVE-2021-46759
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 the ASP (AMD Secure Processor) bootloader accessible memory to a serial port, resulting in a potential loss of integrity. • https://www.amd.com/en/corporate/product-security/bulletin/AMD-SB-4001 • CWE-787: Out-of-bounds Write •
CVE-2021-46754
https://notcve.org/view.php?id=CVE-2021-46754
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. • https://www.amd.com/en/corporate/product-security/bulletin/AMD-SB-4001 https://www.amd.com/en/corporate/product-security/bulletin/AMD-SB-5001 • CWE-20: Improper Input Validation •
CVE-2021-46753
https://notcve.org/view.php?id=CVE-2021-46753
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 overwrite data structures leading to a potential loss of confidentiality and integrity. • https://www.amd.com/en/corporate/product-security/bulletin/AMD-SB-4001 •
CVE-2021-46749
https://notcve.org/view.php?id=CVE-2021-46749
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 potential denial of service. • https://www.amd.com/en/corporate/product-security/bulletin/AMD-SB-4001 • CWE-125: Out-of-bounds Read •
CVE-2021-26316
https://notcve.org/view.php?id=CVE-2021-26316
