CVSS v3.1 |
| 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. |
| Improper Prevention of Lock Bit Modification in SEV firmware could allow a privileged attacker to downgrade firmware potentially resulting in a loss of integrity. |
| A NULL pointer dereference in AMD Crash Defender could allow an attacker to write a NULL output to a log file potentially resulting in a system crash and loss of availability. |
| 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. |
| Type confusion in the AMD Secure Processor (ASP) could allow an attacker to pass a malformed argument to the External Global Memory Interconnect Trusted Agent (XGMI TA) leading to a memory safety violation potentially resulting in loss of confidentiality, integrity, or availability. |
| 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 bound check within AMD CPU microcode can allow a malicious guest to write to host memory, potentially resulting in loss of integrity. |
| 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 input validation in AMD Graphics Driver could allow an attacker to supply a specially crafted pointer, potentially leading to arbitrary code execution. |
| 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. |
| Type confusion in the ASP could allow an attacker to pass a malformed argument to the Reliability, Availability, and Serviceability trusted application (RAS TA) potentially leading to a read or write to shared memory resulting in loss of confidentiality, integrity, or availability. |
| 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. |
| Missing Checks in certain functions related to RMP initialization can allow a local admin privileged attacker to cause misidentification of I/O memory, potentially resulting in a loss of guest memory 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. |
| An unintended proxy or intermediary in the AMD power management firmware (PMFW) could allow a privileged attacker to send malformed messages to the system management unit (SMU) potentially resulting in arbitrary code execution. |
| Improper input validation in the AMD Graphics Driver could allow an attacker to supply a specially crafted pointer, potentially leading to arbitrary writes or denial of service. |
| Insufficient or Incomplete Data Removal in Hardware Component in SEV firmware doesn't fully flush IOMMU. This can potentially lead to a loss of confidentiality and integrity in guest memory. |
| Improper handling of direct memory writes in the input-output memory management unit could allow a malicious guest virtual machine (VM) to flood a host with writes, potentially causing a fatal machine check error resulting in denial of service. |
| 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. |
| Improper validation of an array index in the AMD graphics driver software could allow an attacker to pass malformed arguments to the dynamic power management (DPM) functions resulting in an out of bounds read and loss of availability. |
