How to fix?

Upgrade SLES:15.0 wireshark to version 2.4.8-3.6.1 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 SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the MMSE dissector could go into an infinite loop. This was addressed in epan/proto.c by adding offset and length validation.
