The Wireshark Foundation released version 4.6.5 to address over 40 security flaws — notably several critical vulnerabilities that can enable arbitrary code execution when Wireshark parses maliciously malformed packets or crafted capture files (CVE-2026-5402, CVE-2026-5403, CVE-2026-5405, CVE-2026-5656) — and numerous denial-of-service issues; administrators and analysts are urged to upgrade immediately, although no active exploitation has been reported.
