Short explanation
CVE-2026-89208 is an out-of-bounds read vulnerability identified in certain Siemens Capital Embedded AR Classic and Desigo products. It stems from improper input bounds validation prior to accessing packet data. An unauthenticated remote attacker can trigger this issue.
This vulnerability allows remote attackers to trigger memory reads outside intended packet boundaries. It increases the risk of sensitive data exposure and leaves affected systems vulnerable to network-based attacks.
What should be done?
- Monitor vendor security advisories
- Apply available updates provided for affected Siemens products
- Review network access controls
