Wireshark CVE-2026-6534

Upgrade Wireshark to version 4.6.5 or later (for the 4.6.x branch) or 4.4.15 or later (for the 4.4.x branch) to obtain the patched dissector code. Patch availability is confirmed by the Wireshark security advisory at https://www.wireshark.org/security/wnpa-sec-2026-27.html. As a temporary workaround for users unable to patch immediately, disable or remove the USB HID protocol dissector from Wireshark's dissector table if capture files containing USB traffic are not regularly analyzed - this eliminates the trigger for the infinite loop but may limit visibility into USB HID protocol details. Alternatively, restrict opening of capture files from untrusted sources and avoid processing PCAP files from suspicious origins until patched versions are deployed. The recommended approach is patching, as it is straightforward and has no operational drawbacks.
