CVSS v3.1 |
| 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. |
| AMD System Management Unit (SMU) may experience a heap-based overflow which may result in a loss of resources. |
| 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. |
| Insufficient validation of guest context in the SNP Firmware could lead to a potential loss of guest confidentiality. |
| 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 |
| A timing and power-based side channel attack leveraging the x86 PREFETCH instructions on some AMD CPUs could potentially result in leaked kernel address space information. |
| Failure to verify the protocol in SMM may allow an attacker to control the protocol and modify SPI flash resulting in a potential arbitrary code execution. |
| 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. |
| Potential floating point value injection in all supported CPU products, in conjunction with software vulnerabilities relating to speculative execution with incorrect floating point results, may cause the use of incorrect data from FPVI and may result in data leakage. |
| Potential speculative code store bypass in all supported CPU products, in conjunction with software vulnerabilities relating to speculative execution of overwritten instructions, may cause an incorrect speculation and could result in data leakage. |
| 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. |
| The AUEPLauncher service in Radeon AMD User Experience Program Launcher through 1.0.0.1 on Windows allows elevation of privilege by placing a crafted file in %PROGRAMDATA%\AMD\PPC\upload and then creating a symbolic link in %PROGRAMDATA%\AMD\PPC\temp that points to an arbitrary folder with an arbitrary file name. |
| An exploitable code execution vulnerability exists in the Shader functionality of AMD Radeon DirectX 11 Driver atidxx64.dll 26.20.15019.19000. An attacker can provide a a specially crafted shader file to trigger this vulnerability, resulting in code execution. This vulnerability can be triggered from a HYPER-V guest using the RemoteFX feature, leading to executing the vulnerable code on the HYPER-V host (inside of the rdvgm.exe process). Theoretically this vulnerability could be also triggered from web browser (using webGL and webassembly). |
