CVE-2026-6524

A flaw was found in Wireshark, a widely used network protocol analyzer. A remote attacker could exploit a vulnerability within the MySQL protocol dissector, the part of the software that interprets MySQL network communications. This could lead to a denial of service, causing the Wireshark application to crash and 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, avoid opening untrusted capture files or analyzing untrusted network traffic with Wireshark. Additionally, the MySQL dissector can be disabled to prevent processing of MySQL protocol data. This can be done by navigating to "Analyze > Enabled Protocols..." in Wireshark and unchecking "MySQL". This action does not require a restart of the Wireshark application.
