CVSS v3.1 |
| Linux kernel 2.6.18, and possibly other versions, when running on AMD64 architectures, allows local users to cause a denial of service (crash) via certain ptrace calls. |
| A missing lock verification in AMD Secure Processor (ASP) firmware may permit a locally authenticated attacker with administrative privileges to alter MMIO routing on some Zen 5-based products, potentially compromising guest system integrity. |
| Insufficient checks of the RMP on host buffer access in IOMMU may allow an attacker with privileges and a compromised hypervisor to trigger an out of bounds condition without RMP checks, resulting in a potential loss of confidential guest integrity. |
| FreeBSD 5.x to 5.4 on AMD64 does not properly initialize the IO permission bitmap used to allow user access to certain hardware, which allows local users to bypass intended access restrictions to cause a denial of service, obtain sensitive information, and possibly gain privileges. |
| 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. |
| Improper input validation within the XOCL driver may allow a local attacker to generate an integer overflow condition, potentially resulting in crash or denial of service. |
| An out-of-bounds read in the ASP could allow a privileged attacker with access to a malicious bootloader to potentially read sensitive memory resulting in loss of confidentiality. |
| Improper input validation in Satellite Management Controller (SMC) may allow an attacker with privileges to manipulate Redfish® API commands to remove files from the local root directory, potentially resulting in data corruption. |
| Improper input validation in IOMMU could allow a malicious hypervisor to reconfigure IOMMU registers resulting in loss of guest data integrity. |
| Improper handling of overlap between the segmented reverse map table (RMP) and system management mode (SMM) memory could allow a privileged attacker corrupt or partially infer SMM memory resulting in loss of integrity or confidentiality. |
| An out of bounds write in the Linux graphics driver could allow an attacker to overflow the buffer potentially resulting in loss of confidentiality, integrity, or availability. |
| 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. |
| Improper access control in AMD Secure Encrypted Virtualization (SEV) firmware could allow a malicious hypervisor to bypass RMP protections, potentially resulting in a loss of SEV-SNP guest memory integrity. |
| Improper system call parameter validation in the Trusted OS may allow a malicious driver to perform mapping or unmapping operations on a large number of pages, potentially resulting in kernel memory corruption. |
| Improper isolation of shared resources on System-on-a-chip (SOC) could a privileged attacker to tamper with the contents of the PSP reserved DRAM region potentially resulting in loss of confidentiality and integrity. |
| Improper handling of insufficiency privileges in the ASP could allow a privileged attacker to modify Translation Map Registers (TMRs) potentially resulting in loss of confidentiality or integrity. |
| The Secure Flag passed to Versal™ Adaptive SoC’s Trusted Firmware for Cortex®-A processors (TF-A) for Arm’s Power State Coordination Interface (PSCI) commands were incorrectly set to secure instead of using the processor’s actual security state. This would allow the PSCI requests to appear they were from processors in the secure state instead of the non-secure state. |
| Improper access control within AMD SEV-SNP could allow an admin privileged attacker to write to the RMP during SNP initialization, potentially resulting in a loss of SEV-SNP guest memory integrity. |
| Improper key usage control in AMD Secure Processor
(ASP) may allow an attacker with local access who has gained arbitrary code
execution privilege in ASP to
extract ASP cryptographic keys, potentially resulting in loss of
confidentiality and integrity. |
| An integer overflow in the SMU could allow a privileged attacker to potentially write memory beyond the end of the reserved dRAM area resulting in loss of integrity or availability. |
