Does this matter?

Lower severity and a low EPSS score (0.14%). Track it; it rarely justifies an emergency change on its own.

Description

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.
