Vulnerabilidades do AMD AMD Ryzen™ 5000 Series Desktop Processors

An observable timing discrepancy in the ASP could allow a privileged attacker to perform a brute-force attack against the hash message authentication code, allowing the input of an arbitrary message, potentially leading to a loss of data integrity.

Insecure default configuration state of DDR5 memory module by AGESA Bootloader Firmware could allow an attacker with local user privilege to abuse the unprotected PMIC interface to create a permanent denial of service condition or affect the integrity of the memory module.

Improper Input validation in the AMD Secure Processor (ASP) PCI driver may allow a local attacker to create a buffer overflow condition, potentially resulting in a crash or denial of service

Improper privilege management in the KVM key download component could allow an attacker to swap tokens and download sensitive keys, potentially resulting in unauthorized access to privileged resources and loss of confidentiality.

Missing authentication in the KVM key download endpoint could allow an unauthenticated attacker with knowledge of the exposed URL to retrieve sensitive keys, potentially leading to loss of confidentiality.

Improper restriction of operations within the bounds of a memory buffer in PCIe® Link could allow an attacker with access to a guest virtual machine to potentially perform a denial of service attack against the host resulting in loss of availability.

Insufficient input parameter sanitization in AMD Secure Processor (ASP) Boot Loader (legacy recovery mode only) could allow an attacker to write out-of-bounds to corrupt Secure DRAM potentially resulting in denial of service.
