Last modified Jun 17, 2026

CVE-2025-9612 is a medium-severity vulnerability rated 5.1/10 on the CVSS scale. 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.. EPSS estimates a 0.13% chance of exploitation in the next 30 days.
