CVSS v3.1 |
| Missing authorization in AMD RomArmor could allow an attacker to bypass ROMArmor protections during system resume from a standby state, potentially resulting in a loss of confidentiality and integrity. |
| Improper initialization of CPU cache memory could allow a privileged attacker with hypervisor access to overwrite SEV-SNP guest memory resulting in loss of data integrity. |
| Improper input validation in system management mode (SMM) could allow a privileged attacker to overwrite stack memory leading to arbitrary code execution. |
| Improper Prevention of Lock Bit Modification in SEV firmware could allow a privileged attacker to downgrade firmware potentially resulting in a loss of integrity. |
| Improper isolation of shared resources on a system on a chip by a malicious local attacker with high privileges could potentially lead to a partial loss of integrity. |
| A buffer overflow in the AMD Secure Processor (ASP) bootloader could allow an attacker to overwrite memory, potentially resulting in privilege escalation and arbitrary code execution. |
| A buffer overflow with Xilinx Run Time Environment may allow a local attacker to read or corrupt data from the advanced extensible interface (AXI), potentially resulting in loss of confidentiality, integrity, and/or availability. |
| Improper access control in secure encrypted virtualization (SEV) could allow a privileged attacker to write to the reverse map page (RMP) during secure nested paging (SNP) initialization, potentially resulting in a loss of guest memory confidentiality and integrity. |
| Failure to validate the address and size in TEE (Trusted Execution Environment) may allow a malicious x86 attacker to send malformed messages to the graphics mailbox resulting in an overlap of a TMR (Trusted Memory Region) that was previously allocated by the ASP bootloader leading to a potential loss of integrity. |
| Inadequate lock protection within Xilinx Run time may allow a local attacker to trigger a Use-After-Free condition potentially resulting in loss of confidentiality or availability |
| A bug within some AMD CPUs could allow a local admin-privileged attacker to run a SEV-SNP guest using stale TLB entries, potentially resulting in loss of data integrity. |
| A Speculative Race Condition (SRC) vulnerability that impacts modern CPU architectures supporting speculative execution (related to Spectre V1) has been disclosed. An unauthenticated attacker can exploit this vulnerability to disclose arbitrary data from the CPU using race conditions to access the speculative executable code paths. |
| Use of an uninitialized variable in the ASP could allow an attacker to access leftover data from a trusted execution environment (TEE) driver, potentially leading to loss of confidentiality. |
| Improper input validation for DIMM serial presence detect (SPD) metadata could allow an attacker with physical access, ring0 access on a system with a non-compliant DIMM, or control over the Root of Trust for BIOS update, to bypass SMM isolation potentially resulting in arbitrary code execution at the SMM level. |
| A use after free in the SEV firmware could allow a malicous hypervisor to activate a migrated guest with the SINGLE_SOCKET policy on a different socket than the migration agent potentially resulting in loss of integrity. |
| Insufficient parameter sanitization in TEE SOC Driver could allow an attacker to issue a malformed DRV_SOC_CMD_ID_SRIOV_SPATIAL_PART and cause read or write past the end of allocated arrays, potentially resulting in a loss of platform integrity or denial of service. |
| Improper input validation in the SMM handler could allow an attacker with Ring0 access to write to SMRAM and modify execution flow for S3 (sleep) wake up, potentially resulting in arbitrary code execution. |
| Improper input validation in IOMMU could allow a malicious hypervisor to reconfigure IOMMU registers resulting in loss of guest data integrity. |
| A Time-of-check time-of-use (TOCTOU) race condition in the SMM communications buffer could allow a privileged attacker to bypass input validation and perform an out of bounds read or write, potentially resulting in loss of confidentiality, integrity, or availability. |
| Improper input validation in the SMM communications buffer could allow a privileged attacker to perform an out of bounds read or write to SMRAM potentially resulting in loss of confidentiality or integrity. |
