CVE-2026-5655: CWE-416: Use After Free in Wireshark Foundation Wireshark
SDP protocol dissector crash in Wireshark 4.6.0 to 4.6.4 allows denial of service
AI Analysis
Technical Summary
This vulnerability involves a use-after-free condition (CWE-416) in the SDP protocol dissector component of Wireshark versions 4.6.0 through 4.6.4. When processing malformed SDP packets, the application may crash, leading to denial of service. The CVSS 3.1 vector indicates the attack requires local access with low complexity, no privileges, and user interaction, affecting only availability. No official fix or patch has been confirmed as of the published date.
Potential Impact
Successful exploitation causes a denial of service by crashing Wireshark when it processes crafted SDP protocol data. There is no impact on confidentiality or integrity. The attack requires local access and user interaction, limiting the attack surface. No known exploits are reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should avoid opening untrusted SDP protocol data in affected Wireshark versions. Monitor Wireshark Foundation advisories for updates.
