CVE-2026-102413

Uncaught Exception (CWE-248) in Elastic Endpoint can lead to denial of service via a specially crafted file name. When Elastic Defend's Elastic Endpoint component processes a file name under certain system locale configurations (including Chinese, Japanese, and Korean locales) on Windows, an unhandled exception can occur during file-path handling. This causes the Elastic Endpoint process to crash and restart repeatedly, which can degrade or disable Elastic Defend's real-time malware prevention and behavioral detection capabilities on the affected host for as long as the condition persists.
