CVE-2025-9612 is a medium-severity flaw (CVSS 5.1) affecting pci express integrity and data encryption. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

An issue was discovered in the PCI Express (PCIe) Integrity and Data Encryption (IDE) specification, where insufficient guidance on Transaction Layer Packet (TLP) ordering and tag uniqueness may allow encrypted packets to be replayed or reordered without detection. This can enable local or physical attackers on the PCIe bus to violate data integrity protections.
