Vulnerabilities

AMD System Management Unit (SMU) may experience a heap-based overflow which may result in a loss of resources.

A potential vulnerability exists in AMD Platform Security Processor (PSP) that may allow an attacker to zero any privileged register on the System Management Network which may lead to bypassing SPI ROM protections.

A side effect of an integrated chipset option may be able to be used by an attacker to bypass SPI ROM protections, allowing unauthorized SPI ROM modification.

AMD System Management Unit (SMU) contains a potential issue where a malicious user may be able to manipulate mailbox entries leading to arbitrary code execution.

Insufficient ID command validation in the SEV Firmware may allow a local authenticated attacker to perform a denial of service of the PSP.

Insufficient validation of the AMD SEV Signing Key (ASK) in the SEND_START command in the SEV Firmware may allow a local authenticated attacker to perform a denial of service of the PSP

Persistent platform private key may not be protected with a random IV leading to a potential “two time pad attack”.

AMD System Management Unit (SMU) may experience an integer overflow when an invalid length is provided which may result in a potential loss of resources.

Improper access controls in System Management Unit (SMU) may allow for an attacker to override performance control tables located in DRAM resulting in a potential lack of system resources.
