Three PCIe Encryption Weaknesses Expose PCIe 5.0+ Systems to Faulty Data Handling

Three security vulnerabilities have been disclosed in the Peripheral Component Interconnect Express (PCIe) Integrity and Data Encryption (IDE) protocol specification that could expose a local attacker to serious risks.
The flaws impact PCIe Base Specification Revision 5.0 and onwards in the protocol mechanism introduced by the IDE Engineering Change Notice (ECN), according to the PCI Special
