AI Analysis
Technical Summary
CVE-2026-19695 is a stack-based buffer overflow vulnerability identified in the Gammu DCT3 trace file parser component of Wireshark versions 4.6.0 to 4.6.7. This vulnerability can be triggered by processing specially crafted trace files, leading to a crash of the application and denial of service. The CVSS 3.1 base score is 4.7, reflecting a medium severity with local attack vector, high attack complexity, no privileges required, and user interaction needed. No official fix or patch has been announced as of the publication date.
Potential Impact
Successful exploitation causes a denial of service by crashing Wireshark when parsing malicious Gammu DCT3 trace files. There is no indication of confidentiality or integrity impact. The attack requires local access and user interaction, and has high complexity, limiting exploitability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid opening untrusted Gammu DCT3 trace files in Wireshark versions 4.6.0 through 4.6.7 to mitigate risk.
