AI Analysis
Technical Summary
CVE-2026-93652 is an integer overflow or wraparound vulnerability (CWE-190) in the TCPCLv3 handshake implementation of µD3TN v0.15.0 by D3TN GmbH. The integer overflow leads to a heap overflow, which can be triggered remotely without authentication, resulting in a denial of service. The CVSS v3.1 base score is 7.5, indicating a high severity with network attack vector, low attack complexity, no privileges required, no user interaction, and impact limited to availability.
Potential Impact
Successful exploitation allows remote attackers to cause a denial of service by triggering a heap overflow during the TCPCLv3 handshake. There is no impact on confidentiality or integrity reported. No known exploits are currently in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided at this time. Until a patch is available, consider limiting exposure of the affected service to untrusted networks.
