https://notcve.org/view.php?id=CVE-2021-26371
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. • https://www.amd.com/en/corporate/product-security/bulletin/AMD-SB-3001 https://www.amd.com/en/corporate/product-security/bulletin/AMD-SB-4001 •

https://notcve.org/view.php?id=CVE-2021-26365
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-bounds memory contents. • https://www.amd.com/en/corporate/product-security/bulletin/AMD-SB-4001 • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2021-26354
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 of integrity. • https://www.amd.com/en/corporate/product-security/bulletin/AMD-SB-3001 https://www.amd.com/en/corporate/product-security/bulletin/AMD-SB-4001 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
