Specifically, it looks like the vulnerable code in rtps_util_add_coherent_set_general_cases_case() and rtps_util_detect_coherent_set_end_empty_data_case() was introduced in version 3.1.1 via the following commit: https://gitlab.com/wireshark/wireshark/-/commit/d286b819b7681e2ff9a514d066d2b228d6567607 RHEL-8 ships an older version of wireshark (2.6) which is not affected by this flaw.
