The fix

We hold no Microsoft remediation data for CVE-2026-92701, which normally means it is not a Windows CVE. For non-Microsoft software the fix is the vendor's own updated release, and the affected versions are listed below.

What it is

trusted execution environments. In versions up to and including 0.8.2, the intra-handshake attested TLS (aTLS) Intel TDX verification path does not copy the expected current-session freshness value into the TDX quote-body policy before quote validation, so structurally valid TDX QuoteV4 Evidence is accepted without checking that its REPORT_DATA field matches the reportData expected for the current session. A relying party using this path can therefore accept Evidence with a mismatched or reused reportData and release application data after the handshake, enabling session-misbinding to an unintended attestation context. The issue is fixed in version 0.9.0.
