A vulnerability was discovered in the PCI Express (PCIe) Integrity and Data Encryption (IDE) specification, where insufficient guidance on tag reuse after completion timeouts 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.
