Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (3.11%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

In Wireshark 3.2.0 to 3.2.1, 3.0.0 to 3.0.8, and 2.6.0 to 2.6.14, the EAP dissector could crash. This was addressed in epan/dissectors/packet-eap.c by using more careful sscanf parsing.
