CVE-2026-100835

Contrast before 1.16.0 is susceptible to remote attestation relay attacks. Contrast accepted any TEE attestation report that verified correctly and contained the expected firmware patch levels and software measurements, regardless of which machine produced it, so attestation was not bound to...

CVE-2026-100835

Contrast versions prior to 1.16.0 are vulnerable to a remote attestation relay attack . The root cause is that the software accepts any valid TEE attestation report containing the correct firmware patch levels and software measurements without binding the attestation to specific, physically trust...

PT-2026-53418

Impact This vulnerability involves a critical gap in the cryptographic verification process within the dcap-qvl. The library fetches QE Identity collateral including qe identity, qe identity signature, and qe identity issuer chain from the PCCS. However, it skips to verify the QE Identity signatu...

CVE-2026-12681

Improper Validation of Specified Index, Position, or Offset in Input vulnerability in Google go-attestation. parseEfiSignatureList does not advance the buffer past vendor bytes before reading entries. For hashSHA256SigGUID lists, this allows attacker-controlled vendor header bytes to be appended ...

CVE-2026-12681

Summary: CVE-2026-12681 affects Google go-attestation prior to 0.6.1. The issue arises in parseEfiSignatureList(): the buffer is not advanced past vendor bytes before reading entries, enabling attacker-controlled vendor header bytes to be appended to the trusted SHA256 hash list. A crafted TPM ev...
