Loading vulnerability…
CVE-2025-9613 is a vulnerability in the PCI Express (PCIe) Integrity and Data Encryption (IDE) specification, affecting PCIe Base Specification Revision 5.0 and later. The flaw arises from insufficient guidance on tag reuse after completion timeouts, which may allow multiple outstanding Non-Posted Requests to share the same tag. This tag aliasing condition can result in completions being delivered to the wrong security context, potentially compromising data integrity and confidentiality. The vulnerability is specification-level and impacts hardware and firmware implementations of PCIe IDE, particularly in environments where data integrity is critical.
