Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.62%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In Wireshark 2.4.0 to 2.4.4, the DOCSIS protocol dissector could crash. This was addressed in plugins/docsis/packet-docsis.c by removing the recursive algorithm that had been used for concatenated PDUs.
