Summary

In Google go-attestation up to version 0.6.1, there is an uncontrolled recursion vulnerability in the Windows SIPA event log parser, allowing an attacker to cause a denial of service (DoS) by submitting a crafted event log with deeply nested elamAggregation headers. This leads to stack overflow and immediate crash of the application.

Risk Assessment

An attacker can remotely crash the verification application, potentially disrupting security processes that rely on go-attestation.

Recommendation

Update go-attestation to a patched version or restrict processing of untrusted event logs.

Other vulnerabilities in Google go-attestation

CVE-2026-12681High
In a vulnerability in Google go-attestation, the parseEfiSignatureList() function improperly validates indices, allowing attacker-controlled vendor header bytes to be appended to the trusted SHA256 hash list. This could lead to a remote attestation verifier accepting a compromised boot state.

Original NVD description (English source)

An uncontrolled recursion vulnerability in the Windows SIPA event log parser of Google go-attestation versions up to and including 0.6.1 allows an attacker to cause a denial of service (DoS). The (*WinEvents).readELAMAggregation function recurses for every nested elamAggregation sub-event without enforcing a maximum recursion depth limit, while the size guard is bypassed on recursive execution paths. By submitting a crafted Windows event log containing deeply nested elamAggregation headers, an attacker can exhaust the goroutine call stack, triggering an unrecoverable fatal runtime error (stack overflow) that immediately crashes the verifier application.
