Miggo AIRoot Cause AnalysisI was unable to find the exact commit that fixes the vulnerability. The CVE and advisory details appear to be fabricated, with a future publication date, which prevented me from finding a real-world patch. However, based on the detailed description of the vulnerability, I can still identify the likely vulnerable functions.

This indicates that a DNS resolution callback, executed within runPostCallbacks, is triggering new DNS resolutions, leading to a re-entrancy issue that corrupts the DNS cache iterators.
Based on this, I have identified the following functions as vulnerable:
