Hi, The following vulnerability was published for golang-github-google-go-attestation. CVE-2026-12681[0]: | 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 to the trusted SHA256 hash list. A | crafted TPM event log could inject arbitrary SHA256 hashes into the | verifier's trusted measurement database, enabling a remote | attestation verifier to accept a compromised boot state. This issue | affects go-attestation: through 0.6.0. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
