In Wireshark 3.2.0 to 3.2.5, the Kafka protocol dissector could crash. This was addressed in epan/dissectors/packet-kafka.c by avoiding a double free during LZ4 decompression.
The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
