The Cosmos SDK is used for Inter-Blockchain Communication Protocol (IBC) applications and middleware. The packet-forward-middleware module is an IBC middleware module built for Cosmos blockchains utilizing the IBC protocol allowing routing of incoming IBC packets from a source chain to a destination chain. The `packet-forward-middleware` module is vulnerable to potential chain-halt due to error non-determinism. Patches Please patch at your earliest convenience by applying one of the following patch versions, respective to the chain's ibc-go major version: v4.1.1 v5.2.1 v6.1.1
