How to fix?

Upgrade Alpine:3.17 wireshark to version 2.2.6-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream wireshark package and not the wireshark package as distributed by Alpine. See How to fix? for Alpine:3.17 relevant fixed versions and status.

In Wireshark 2.2.0 to 2.2.5 and 2.0.0 to 2.0.11, the RPC over RDMA dissector could go into an infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-rpcrdma.c by correctly checking for going beyond the maximum offset.
