Cross-domain data exposure via stale posted writes
Published Dec 9, 2025 · Updated Dec 10, 2025
Improper integrity validation in PCI Express IDE allows attackers to expose or overwrite data across trusted domains through stale writes. During device rebinding, a security module that fails to flush or re-key an IDE stream can deliver delayed MMIO or DMA writes from the prior context to the newly bound one. Exploitation requires control of low-level PCIe traffic, such as a malicious programmable switch, and affects confidentiality or integrity rather than availability.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <6.5-Rev7.0
- Affected versionversion=0 <7.1-Rev7.0
