Failure to validate the integer operand in ASP (AMD Secure Processor) bootloader may allow an attacker to introduce an integer overflow in the L2 directory table in SPI flash resulting in a potential denial of service. No validar el operando entero en el cargador de arranque ASP (AMD Secure Processor) puede permitir que un atacante introduzca un desbordamiento de enteros en la tabla del directorio L2 en SPI flash, lo que resulta en una posible denegación de servicio. • https://www.amd.com/en/corporate/product-security/bulletin/AMD-SB-1031 • CWE-190: Integer Overflow or Wraparound •

IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure. IBPB no puede evitar que las predicciones de sucursales de retorno sean especificadas por objetivos de sucursales anteriores a IBPB, lo que lleva a una posible divulgación de información. • http://www.openwall.com/lists/oss-security/2022/11/10/2 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NTQMPJC5N6XJYQ232OZFLK47HVZNRBY3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YTMITQBGC23MSDHUCAPCVGLMVXIBXQTQ https://security.gentoo.org/glsa/202402-07 https://www.amd.com/en/corporate/product-security/bulletin/amd-sb-1040 https://www.debian.org/security/2023/dsa-5378 •

Execution unit scheduler contention may lead to a side channel vulnerability found on AMD CPU microarchitectures codenamed “Zen 1”, “Zen 2” and “Zen 3” that use simultaneous multithreading (SMT). By measuring the contention level on scheduler queues an attacker may potentially leak sensitive information. La contención del planificador de la unidad de ejecución puede conllevar a una vulnerabilidad de canal lateral encontrada en las microarquitecturas de CPU de AMD con nombre en código "Zen 1", "Zen 2" y "Zen 3" que usan multihilo simultáneo (SMT). Al medir el nivel de contención en las colas del programador, un atacante puede filtrar potencialmente información confidencial • https://www.amd.com/en/corporate/product-security/bulletin/amd-sb-1039 • CWE-203: Observable Discrepancy •

A malformed SMI (System Management Interface) command may allow an attacker to establish a corrupted SMI Trigger Info data structure, potentially leading to out-of-bounds memory reads and writes when triggering an SMI resulting in a potential loss of resources. Un comando SMI (System Management Interface) malformado puede permitir a un atacante establecer una estructura de datos SMI Trigger Info corrupta, conllevando potencialmente a lecturas y escrituras de memoria fuera de límites cuando es desencadenado un SMI resultando en una potencial pérdida de recursos • https://www.amd.com/en/corporate/product-security/bulletin/amd-sb-1027 • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
