# AMD SEV firmware: improper resource reuse lets hypervisor write protected memory

Link for people: https://infrastack.ai/live/CVE-2025-52535 (this .md is for agents)

AMD Secure Encrypted Virtualization (SEV) firmware reuses a resource improperly, letting an attacker with hypervisor access write to Reverse Map Table (RMP) protected memory. The result can be loss of guest memory integrity for virtual machines.

_Summary, check and fix written by a model from the sources; labelled as such._
