The vulnerability identified as CVE-2026-6092 concerns a cryptographic implementation flaw related to the handling of message authentication and encryption order. Specifically, when the HAVE_ENCRYPT_THEN_MAC option is configured, the implementation may revert to using MAC-then-Encrypt rather than strictly enforcing Encrypt-then-MAC. This fallback could undermine the security properties expected from the Encrypt-then-MAC approach, potentially affecting data integrity and confidentiality assurances. The issue is categorized under CWE-757, indicating reliance on potentially unsafe or incorrect cryptographic practices.

The impact is considered low severity. The fallback to MAC-then-Encrypt instead of enforcing Encrypt-then-MAC may reduce the cryptographic strength of the system, but no known exploits are reported in the wild. The vulnerability could theoretically allow attackers to exploit weaknesses in the MAC-then-Encrypt approach, but the practical risk is limited due to the configuration requirement and the complexity of exploitation.

No patch or official fix information is currently available. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is provided, users should review their cryptographic configuration to ensure that Encrypt-then-MAC is properly enforced and avoid relying on the HAVE_ENCRYPT_THEN_MAC fallback behavior. Monitoring vendor advisories for updates is recommended.
