CVE-2025-9612
📋 TL;DR
This CVE describes a vulnerability in the PCI Express IDE specification where insufficient guidance on packet ordering and tag uniqueness may allow encrypted packets to be replayed or reordered without detection. This enables local or physical attackers on the PCIe bus to violate data integrity protections. Systems using PCIe IDE encryption for data protection are affected.
💻 Affected Systems
- Systems implementing PCIe IDE specification for encryption
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could manipulate encrypted PCIe traffic to corrupt or replay data, potentially compromising system integrity, enabling data tampering, or facilitating privilege escalation attacks.
Likely Case
Local attackers with physical or privileged access could manipulate PCIe traffic to bypass integrity checks, potentially leading to data corruption or unauthorized data access.
If Mitigated
With proper access controls and monitoring, the impact is limited to denial of service or data corruption rather than full system compromise.
🎯 Exploit Status
Exploitation requires physical or privileged access to PCIe bus and understanding of PCIe IDE implementation details.
