CVSS v3.1 |
| Failure to validate VM_HSAVE_PA during SNP_INIT may result in a loss of memory integrity. |
| Insufficient input validation in the SNP_GUEST_REQUEST command may lead to a potential data abort error and a denial of service. |
| A bug with the SEV-ES TMR may lead to a potential loss of memory integrity for SNP-active VMs. |
| Failure to validate SEV Commands while SNP is active may result in a potential impact to memory integrity. |
| Persistent platform private key may not be protected with a random IV leading to a potential “two time pad attack”. |
| 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 |
| When the AMD Platform Security Processor (PSP) boot rom loads, authenticates, and subsequently decrypts an encrypted FW, due to insufficient verification of the integrity of decrypted image, arbitrary code may be executed in the PSP when encrypted firmware images are used. |
| Failure to flush the Translation Lookaside Buffer (TLB) of the I/O memory management unit (IOMMU) may lead an IO device to write to memory it should not be able to access, resulting in a potential loss of integrity. |
| In the AMD SEV/SEV-ES feature, memory can be rearranged in the guest address space that is not detected by the attestation mechanism which could be used by a malicious hypervisor to potentially lead to arbitrary code execution within the guest VM if a malicious administrator has access to compromise the server hypervisor. |
| A potential denial of service (DoS) vulnerability exists in the integrated chipset that may allow a malicious attacker to hang the system when it is rebooted. |
| The lack of nested page table protection in the AMD SEV/SEV-ES feature could potentially lead to arbitrary code execution within the guest VM if a malicious administrator has access to compromise the server hypervisor. |
| AMD EPYC™ Processors contain an information disclosure vulnerability in the Secure Encrypted Virtualization with Encrypted State (SEV-ES) and Secure Encrypted Virtualization with Secure Nested Paging (SEV-SNP). A local authenticated attacker could potentially exploit this vulnerability leading to leaking guest data by the malicious hypervisor. |
| 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. |
| Race condition in ASP firmware could allow less privileged x86 code to perform ASP SMM (System Management Mode) operations. |
| Insufficient input validation in ASP firmware for discrete TPM commands could allow a potential loss of integrity and denial of service. |
| Insufficient validation of BIOS image length by ASP Firmware could lead to arbitrary code execution. |
