A bug in AMD CPU’s core logic may allow for an attacker, using specific code from an unprivileged VM, to trigger a CPU core hang resulting in a potential denial of service. AMD believes the specific code includes a specific x86 instruction sequence that would not be generated by compilers. Un bug en la lógica del núcleo de la CPU de AMD puede permitir a un atacante, usando un código específico de una máquina virtual no privilegiada, desencadenar un cuelgue del núcleo de la CPU resultando en una potencial denegación de servicio. AMD cree que el código específico incluye una secuencia de instrucciones x86 específica que no sería generada por los compiladores • https://www.amd.com/en/corporate/product-security/bulletin/amd-sb-1027 https://www.amd.com/en/corporate/product-security/bulletin/amd-sb-1028 •

A malicious or compromised UApp or ABL may coerce the bootloader into corrupting arbitrary memory potentially leading to loss of integrity of data. Una UApp o ABL maliciosa o comprometida puede coaccionar al administrador de arranque para que corrompa la memoria arbitraria, lo que podría conllevar a una pérdida de la integridad de los datos • https://www.amd.com/en/corporate/product-security/bulletin/amd-sb-1027 •
