CVE-2026-5653 [HIGH] CWE-476 wireshark: Wireshark: Denial of Service via DCP-ETSI protocol dissector crash
wireshark: Wireshark: Denial of Service via DCP-ETSI protocol dissector crash
A flaw was found in Wireshark. A remote attacker could exploit a vulnerability in the DCP-ETSI protocol dissector, which is responsible for analyzing network traffic, to cause a crash. This could lead to a denial of service (DoS), making the application unavailable to users.
Mitigation: To reduce the risk of exploitation, users should avoid opening untrusted network capture files or analyzing network traffic from untrusted sources with Wireshark. Additionally, consider running Wireshark in a sandboxed environment to further isolate potential impacts.
