Insufficient validation in parsing Owner's Certificate Authority (OCA) certificates in SEV (AMD Secure Encrypted Virtualization) and SEV-ES user application can lead to a host crash potentially resulting in denial of service.

Insufficient address validation, may allow an attacker with a compromised ABL and UApp to corrupt sensitive memory locations potentially resulting in a loss of integrity or availability.
Insufficient input validation of mailbox data in the SMU may allow an attacker to coerce the SMU to corrupt SMRAM, potentially leading to a loss of integrity and privilege escalation.
A compromised or malicious ABL or UApp could send a SHA256 system call to the bootloader, which may result in exposure of ASP memory to userspace, potentially leading to information disclosure.
Certain size values in firmware binary headers could trigger out of bounds reads during signature validation, leading to denial of service or potentially limited leakage of information about out-of-bounds memory contents.
A TOCTOU in ASP bootloader may allow an attacker to tamper with the SPI ROM following data read to memory potentially resulting in S3 data corruption and information disclosure.
Insufficient bounds checking in ASP may allow an attacker to issue a system call from a compromised ABL which may cause arbitrary memory values to be initialized to zero, potentially leading to a loss of integrity.
Insufficient input validation in the SMU may allow an attacker to corrupt SMU SRAM potentially leading to a loss of integrity or denial of service.
Insufficient input validation in ASP may allow an attacker with a compromised SMM to induce out-of-bounds memory reads within the ASP, potentially leading to a denial of service.
A malicious or compromised UApp or ABL can send a malformed system call to the bootloader, which may result in an out-of-bounds memory access that may potentially lead to an attacker leaking sensitive information or achieving code execution.
Improper syscall input validation in AMD TEE (Trusted Execution Environment) may allow an attacker with physical access and control of a Uapp that runs under the bootloader to reveal the contents of the ASP (AMD Secure Processor) bootloader accessible memory to a serial port, resulting in a potential loss of integrity.
Incorrect default permissions in the AMD RyzenTM Master Utility installation directory could allow an attacker to achieve privilege escalation potentially resulting in arbitrary code execution.
Incorrect default permissions in the AMD Management Plugin for the Microsoft® System Center Configuration Manager (SCCM) installation directory could allow an attacker to achieve privilege escalation, potentially resulting in arbitrary code execution.
Incorrect default permissions in the AMD Cloud Manageability Service (ACMS) Software installation directory could allow an attacker to achieve privilege escalation potentially resulting in arbitrary code execution.
Incorrect default permissions in the AMD RyzenTM Master monitoring SDK installation directory could allow an attacker to achieve privilege escalation potentially resulting in arbitrary code execution.
Incorrect default permissions in the AMD Management Console installation directory could allow an attacker to achieve privilege escalation potentially resulting in arbitrary code execution.
Incorrect default permissions in the AMD Provisioning Console installation directory could allow an attacker to achieve privilege escalation, potentially resulting in arbitrary code execution.
Improper validation of array index in Power Management Firmware (PMFW) may allow a privileged attacker to cause an out-of-bounds memory read within PMFW, potentially leading to a denial of service.
A malicious attacker in x86 can misconfigure the Trusted Memory Regions (TMRs), which may allow the attacker to set an arbitrary address range for the TMR, potentially leading to a loss of integrity and availability.
kernel: hw:amd:IOMMU improperly handles certain special address leading to a loss of guest integrity
IOMMU improperly handles certain special address ranges with invalid device table entries (DTEs), which may allow an attacker with privileges and a compromised Hypervisor to induce DTE faults to bypass RMP checks in SEV-SNP, potentially leading to a loss of guest integrity.
