Status: ModifiedHigh (7.5)—

In Wireshark 2.4.0 to 2.4.12 and 2.6.0 to 2.6.6, the RPCAP dissector could crash. This was addressed in epan/dissectors/packet-rpcap.c by avoiding an attempted dereference of a NULL conversation.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
