CVE-2026-18125 is a high-severity out-of-bounds read vulnerability in the Agent component of Ivanti Endpoint Manager. It affects Ivanti Endpoint Manager versions before 2024 SU7, including 2024 SU6 and earlier. The flaw can be triggered remotely by an unauthenticated attacker through crafted input to the agent, causing the agent service to read memory outside the intended bounds and terminate. The issue is described as a denial-of-service condition in the agent service rather than a code-execution vulnerability.
