- Mitigation guidance
- Disable the USB HID protocol dissector when USB HID traffic inspection is not required, or avoid processing capture files from untrusted sources. To disable the protocol dissector in TShark: ``` tshark --disable-protocol usbhid -r capture.pcap ``` To disable the dissector persistently in Wireshark: 1. Open the GUI and select Analyze -> Enabled Protocols. 2. Locate "USB HID" (filter name usbhid) and deselect it. Alternatively, append `usbhid` to the disabled protocols file located at `~/.config/wireshark/disabled_protos`. Caveat: Disabling the USB HID dissector prevents packet decoders from parsing USB HID payload structures, displaying affected packets only as raw USB data.
