CVE-2026-19201— Denial of Service via Unbounded Recursion in go-attestation Windows SIPA Parser

Quick assessment

Affected
Google go-attestation
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Google go-attestation 0.6.1 及更早版本中，Windows SIPA 事件日志解析器存在一个未受控的递归漏洞，攻击者可借此触发服务拒绝（DoS）。 函数会在每个嵌套的 elAMAggregation 子事件中递归执行，且未设置最大递归深度限制，同时在递归执行路径中绕过了大小保护机制。攻击者可通过提交一个包含深层嵌套 elAMAggregation 头部的特制 Windows 事件日志，耗尽协程调用栈，从而触发不可恢复的运行时致命错误（栈溢出），导致验证器应用程序立即崩溃。

Vulnerability Title
Denial of Service via Unbounded Recursion in go-attestation Windows SIPA Parser
Source: CVE Program / CVE List V5
Vulnerability Description
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.
