SEGV in Network_Layer_Conver_PublisherId func
Hello,
While performing fuzzing using oss-fuzz personally, I discovered a crash, and the input value that caused the crash was a simple null reference.
The call stack trace revealed that the issue originated from the process of decoding the input data.
input data: \x01\x7B\x00\x89
Based on my analysis, it seems that there may be a need to carefully consider null value checks for the referenced values during decoding.
I have attached some additional information regarding the fuzzer and provided screenshots. Thank you.
