CVE-2026-76926

A flaw was found in Wireshark. A remote attacker could exploit this by providing a specially crafted BUSMASTER file, which triggers a reachable assertion in the BUSMASTER file parser, leading to an abnormal exit. This could result in a denial of service (DoS), making the application unavailable.

This Low impact denial of service flaw in Wireshark's BUSMASTER file parser requires user interaction to open a specially crafted file. The high attack complexity further reduces the risk, as successful exploitation would only lead to a temporary disruption of the application.

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, users should avoid opening untrusted or specially crafted BUSMASTER files with Wireshark. Exercise caution when handling files from unknown or suspicious sources.
