NVD Description

Note: Versions mentioned in the description apply only to the upstream go-toolset:rhel8/delve package and not the go-toolset:rhel8/delve package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

The HTTP/2 server can refund connection-level flow control twice for the same data: Once when a client resets a stream (refunding data for any sent-but-unread portion of the stream), and again when a request handler reads the buffered data. A malicious client can exploit this to bypass the configured connection-level flow control limit (MaxReceiveBufferPerConnection). Total buffered data is still limited by the concurrent stream limit and stream-level flow control.
