CVE ID :CVE-2026-92701
Published : Sept. 18, 2026, 6:18 p.m. | 50 minutes ago
Description :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.
Severity: 9.1 | CRITICAL
