Detailed vulnerability description
The vulnerability allows a local user to bypass implemented security restrictions.
The vulnerability exists due to insufficient guidance on re-keying and stream flushing during device rebinding a PCIe device to a new Trusted Domain Interface (TDI) as described in PCI Express (PCIe) Base Specification. A local user can violate confidentiality or security objectives, leading to security restrictions bypass.
How to mitigate CVE-2025-9614
The PCI-SIG has issued a Draft Engineering Change Notice (D-ECN) titled “IDE TLP Reordering Enhancement” to the Base Specification Rev 7.0. The D-ECN feature will be included in upcoming PCI specifications (Base 6.5 and 7.1) and can also be used in current Base 5.x systems through standard compliance procedures.
