AI Analysis
Technical Summary
CVE-2026-6530 is a heap-based buffer overflow vulnerability in the DCP-ETSI protocol dissector component of Wireshark versions 4.6.0 through 4.6.4 and 4.4.0 through 4.4.14. This vulnerability leads to a crash of the Wireshark application, causing denial of service. The CVSS 3.1 base score is 5.5, reflecting a medium severity with local attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, and impact limited to availability. No official fix or patch has been documented in the provided data, and no known exploits have been reported.
Potential Impact
Successful exploitation of this vulnerability results in a denial of service by crashing the Wireshark application when processing malformed DCP-ETSI protocol data. There is no reported impact on confidentiality or integrity. The attack requires local access and user interaction to trigger the crash.
Mitigation Recommendations
Patch status is not yet confirmed — check the Wireshark Foundation advisory for current remediation guidance. Until a fix is available, users should exercise caution when analyzing untrusted DCP-ETSI protocol traffic and consider avoiding or disabling this dissector if possible.
