CVE-2026-5655 [HIGH] CWE-237 wireshark: Wireshark: Denial of Service due to SDP protocol dissector crash
wireshark: Wireshark: Denial of Service due to SDP protocol dissector crash
A flaw was found in Wireshark. A local user could be tricked into opening a specially crafted capture file containing Session Description Protocol (SDP) data. Processing this malicious data could lead to a crash in the SDP protocol dissector, resulting in a denial of service for the application.
Mitigation: To mitigate this issue, users should avoid opening untrusted or suspicious capture files with Wireshark. Exercise caution when handling files from unknown sources to prevent accidental application crashes.
