Latest first
- 7.0 High severity
AMD EPYC™ 7003 Series Processors: Improper Check for Unusual or Exceptional Conditions
Improper exception handling in IOMMU could allow an invalidate command to be sent to PCIe devices that do not support Address Translation Cache (ATC), potentially resulting in denial of service.
- 8.4 High severity
AMD EPYC™ 7003 Series Processors: Improper Verification of Cryptographic Signature
Insufficient verification of data authenticity may allow a local attacker to bypass Secure Debug Unlock (SDU), potentially resulting in unauthorized debug access.
- 7.5 High severity
AMD EPYC™ 9004 Series Processors: Exposure of Resource to Wrong Sphere
Incorrect use of boot service in the AMD Platform Configuration Blob (APCB) SMM driver could allow a privileged attacker with local access (Ring 0) to achieve privilege escalation potentially resulting in arbitrary code execution.
- 8.3 High severity
AMD EPYC™ 7001 Series Processors: Improper Restriction of Operations within the Bounds of a Memory Buffer
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.
- 8.7 High severity
AMD EPYC™ 7003 Series Processors: On-Chip Debug and Test Interface With Improper Access Control
Improper Access Control in an on-chip debug interface could allow a privileged attacker to enable a debug interface and potentially compromise data confidentiality or integrity.
- 7.1 High severity
AMD EPYC™ 9004 Series Processors: Improper Access Control for Volatile Memory Containing Boot Code
Improper input validation in system management mode (SMM) could allow a privileged attacker to overwrite stack memory leading to arbitrary code execution.
- 7.5 High severity
AMD Ryzen™ Threadripper™ 3000 Processors: Improper Prevention of Lock Bit Modification
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 re
- 7.9 High severity
AMD EPYC™ 7002 Series Processors: Improper Access Control for Register Interface
Improper register access control in ASP may allow a privileged attacker to perform unauthorized access to ASP’s Crypto Co-Processor (CCP) registers from x86 resulting in potential loss of control of cryptographic key pointer/index leading to loss of integrity
- 10.0 Critical severity
AMD EPYC™ 7003 Series Processors: Improper Initialization
Improper re-initialization of IOMMU during the DRTM event may permit an untrusted platform configuration to persist, allowing an attacker to read or modify hypervisor memory, potentially resulting in loss of confidentiality, integrity, and availability.
