CVE-2021-26371
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 •
CVE-2021-26354
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') •
CVE-2023-20532
https://notcve.org/view.php?id=CVE-2023-20532
Insufficient input validation in the SMU may allow an attacker to improperly lock resources, potentially resulting in a denial of service. Una validación de entrada insuficiente en la SMU puede permitir que un atacante bloquee recursos incorrectamente, lo que podría provocar una denegación de servicio. • https://www.amd.com/en/corporate/product-security/bulletin/AMD-SB-1032 • CWE-20: Improper Input Validation •
CVE-2023-20531
https://notcve.org/view.php?id=CVE-2023-20531
Insufficient bound checks in the SMU may allow an attacker to update the SRAM from/to address space to an invalid value potentially resulting in a denial of service. Las comprobaciones limitadas insuficientes en la SMU pueden permitir que un atacante actualice la SRAM desde/hacia el espacio de direcciones a un valor no válido, lo que podría provocar una denegación de servicio. • https://www.amd.com/en/corporate/product-security/bulletin/AMD-SB-1032 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
