AI Analysis
Technical Summary
CVE-2026-96415 is a stack-based buffer overflow vulnerability (CWE-121) in the Catapult DCT2000 protocol dissector component of Wireshark. It affects versions 4.4.0 to 4.4.18 and 4.6.0 to 4.6.8. The vulnerability can be triggered by processing malformed packets, causing the application to crash and leading to denial of service. The CVSS v3.1 base score is 5.5, indicating a medium severity with local attack vector, low complexity, no privileges required, user interaction required, and impact limited to availability.
Potential Impact
Exploitation of this vulnerability results in denial of service by crashing the Wireshark application when it processes specially crafted Catapult DCT2000 protocol packets. There is no impact on confidentiality or integrity according to the CVSS vector. No known exploits are reported in the wild.
Mitigation Recommendations
