SEV-SNP RMP Initialization Vulnerability , Oct. 13, 2025

Description: Researchers from ETHz reported that a malicious hypervisor could corrupt the Reverse Map Table (RMP) during Secure Nested Paging (SNP) initialization.

AMD reproduced the issue and determined it is due to a race condition that can occur while the AMD Secure Processor (ASP) is initializing the RMP. This attack could allow a malicious hypervisor to manipulate the initial RMP content, potentially resulting in loss of SEV-SNP guest memory integrity. AMD has released mitigations for this vulnerability.

AMD Transient Scheduler Attacks, July 08, 2025

Description: AMD discovered several transient scheduler attacks related to the execution timing of instructions under specific microarchitectural conditions while investigating a Microsoft® report titled “Enter, Exit, Page Fault, Leak: Testing Isolation Boundaries for Microarchitectural Leaks”.

AMD has debugged these patterns and identified a speculative side channel affecting AMD CPUs . In some cases, an attacker may be able to use this timing information to infer data from other contexts, resulting in information leakage.

Zynq™ UltraScale+™ SoC Overwriting Protected Memory Regions Through PMU Firmware, July 01, 2025

Description: In Zynq™ UltraScale+™ devices, the Platform Management Unit (PMU) Firmware is designed to implement runtime (post boot) software services that allow a remote processor to command the PMU to execute cryptographic operations (i.e. AES-GCM/256, SHA3-284, RSA) using the hardened crypto accelerators, programmable logic readback, and eFUSE read and write operations within the Configuration Security Unit (CSU).

The researcher’s paper describes a vulnerability that exists with commanding these runtime services, in that the memory pointers passed with the command are not checked to verify that the requesting processor has access to the memory space.
