CVE-2026-6538

A flaw was found in Wireshark. A remote attacker could exploit a crash in the BEEP (Blocks Extensible Exchange Protocol) dissector by crafting a malicious BEEP packet. This vulnerability leads to a Denial of Service (DoS), causing Wireshark to become unresponsive.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

To mitigate this issue, disable the BEEP protocol dissector in Wireshark. This prevents the application from processing BEEP packets, thereby avoiding the vulnerability. This action can be performed within Wireshark's protocol preferences. Disabling the BEEP dissector will prevent analysis of BEEP protocol traffic.
