How to fix?

Upgrade Alpine:3.17 wireshark to version 2.6.7-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 2.4.0 to 2.4.12 and 2.6.0 to 2.6.6, the RPCAP dissector could crash. This was addressed in epan/dissectors/packet-rpcap.c by avoiding an attempted dereference of a NULL conversation.
