CVE-2024-24476Public exploitNetwork attack vector

Disputed analyzer crash via short address lookup

Published Feb 21, 2024 · Updated Nov 4, 2025

Heap-buffer over-read in Wireshark before 4.2.0 allows remote attackers to crash packet analysis through crafted traffic. The ws_manuf_lookup_str path reads six address bytes even when the packet-derived buffer is shorter, causing the OSS-Fuzz out-of-bounds read. Wireshark states that the report rests on invalid assumptions and that neither 4.2.0 nor any other released version was affected.
