The vulnerability is triggered when a sample recursively spawns a large number of child processes, generating high log volume and exhausting system resources. As a result, key malicious behavior, including PowerShell execution and reverse shell activity, may not be recorded or reported, misleading analysts and compromising the integrity and availability of sandboxed analysis results."}], "lastModified": "2025-10-21T19:31:25.450", "sourceIdentifier": "cve@mitre.org"}
