CVE-2024-21981
https://notcve.org/view.php?id=CVE-2024-21981
Improper key usage control in AMD Secure Processor (ASP) may allow an attacker with local access who has gained arbitrary code execution privilege in ASP to extract ASP cryptographic keys, potentially resulting in loss of confidentiality and integrity. • https://www.amd.com/en/resources/product-security/bulletin/amd-sb-3003.html • CWE-639: Authorization Bypass Through User-Controlled Key •
CVE-2022-23829
https://notcve.org/view.php?id=CVE-2022-23829
A potential weakness in AMD SPI protection features may allow a malicious attacker with Ring0 (kernel mode) access to bypass the native System Management Mode (SMM) ROM protections. Una posible debilidad en las funciones de protección AMD SPI puede permitir que un atacante malicioso con acceso Ring0 (modo kernel) evite las protecciones ROM nativas del modo de administración del sistema (SMM). • https://www.amd.com/en/resources/product-security/bulletin/amd-sb-1041.html • CWE-284: Improper Access Control •
CVE-2023-4969 – GPU kernel implementations susceptible to memory leak
https://notcve.org/view.php?id=CVE-2023-4969
A GPU kernel can read sensitive data from another GPU kernel (even from another user or app) through an optimized GPU memory region called _local memory_ on various architectures. Un kernel de GPU puede leer datos confidenciales de otro kernel de GPU (incluso de otro usuario o aplicación) a través de una región de memoria de GPU optimizada llamada _local memory_ en varias arquitecturas. • https://blog.trailofbits.com https://kb.cert.org/vuls/id/446598 https://registry.khronos.org/OpenCL/specs/3.0-unified/html/OpenCL_API.html#_fundamental_memory_regions https://registry.khronos.org/vulkan/specs/1.3-extensions/html/index.html https://www.kb.cert.org/vuls/id/446598 • CWE-401: Missing Release of Memory after Effective Lifetime •
CVE-2022-23821
https://notcve.org/view.php?id=CVE-2022-23821
Improper access control in System Management Mode (SMM) may allow an attacker to write to SPI ROM potentially leading to arbitrary code execution. Un control de acceso inadecuado en System Management Mode (SMM) puede permitir que un atacante escriba en la ROM SPI, lo que podría provocar la ejecución de código arbitrario. • https://www.amd.com/en/corporate/product-security/bulletin/AMD-SB-4002 https://www.amd.com/en/corporate/product-security/bulletin/AMD-SB-5001 •
CVE-2023-20521
https://notcve.org/view.php?id=CVE-2023-20521
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 service. TOCTOU en el ASP Bootloader puede permitir que un atacante con acceso físico altere los registros ROM SPI después de la verificación del contenido de la memoria, lo que podría provocar una pérdida de confidencialidad o una denegación de servicio. • https://www.amd.com/en/corporate/product-security/bulletin/AMD-SB-3002 https://www.amd.com/en/corporate/product-security/bulletin/AMD-SB-4002 https://www.amd.com/en/corporate/product-security/bulletin/AMD-SB-5001 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
