CVE-2020-9431
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 LTE RRC dissector could leak memory.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.71%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
