Detailsinfo

A vulnerability classified as problematic has been found in Google go-attestation up to 0.6.1. This affects the function (WinEvents).readELAMAggregation of the component Windows SIPA event log parser. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on availability. The summary by CVE is:

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.

It is possible to read the advisory at github.com. This vulnerability is uniquely identified as CVE-2026-19201 since 08/07/2026. The exploitability is told to be easy.
