Root Cause Analysis
The vulnerability manifests in HTTP/2 connection shutdown handling. ServeConn
is the primary HTTP/2 connection handler that manages the state machine and shutdown process()
. The Go vulnerability database (GO-2022-0969) explicitly lists Server.ServeConn
as an affected symbol, and the CVE description specifically references HTTP/2 connection hangs during shutdown sequences. This function
would appear in stack traces when the server is stuck handling a hung connection during exploitation.
