CVE-2025-9612

What is CVE-2025-9612?

A security issue has been identified in the PCI Express (PCIe) Integrity and Data Encryption (IDE) specification. It relates to inadequate guidance regarding the ordering of Transaction Layer Packets (TLP) and the uniqueness of tags. This weakness could permit encrypted packets to be reordered or replayed undetected, thereby potentially allowing local or physical attackers on the PCIe bus to compromise data integrity protections. Organizations utilizing affected PCIe specifications should review their security measures to prevent exploitation of this vulnerability.
