More information #### Details Previously, a channel registered in the mux's chanList is not usable until it is established. A malicious peer was able flood the channel's incomingRequests, deadlocking the entire connection. Now, we add an atomic established state, set when a channel becomes usable. Until such a time, handlePacket drops every packet other than the open confirmation/failure, without blocking and without tearing down the connection. #### Severity Unknown #### References - [https://go.dev/issue/81316](https://go.dev/issue/81316) - [https://go.dev/cl/826504](https://go.dev/cl/826504) - [https://groups.google.com/g/golang-announce/c/1y3fb2np35U](https://groups.google.com/g/golang-announce/c/1y3fb2np35U) This data is provided by [OSV](https://osv.dev/vulnerability/GO-2026-6354) and the [Go Vulnerability Database](https://github.com/golang/vulndb) ([CC-BY 4.0](https://github.com/golang/vulndb#license)).
--- ### Prevent DoS on deadlocked established channel in golang.org/x/crypto/ssh [CVE-2026-56855](https://nvd.nist.gov/vuln/detail/CVE-2026-56855) / [GO-2026-6355](https://pkg.go.dev/vuln/GO-2026-6355)
More information #### Details Previously, after a channel has been established, a malicious peer could send crafted messages that would deadlock the entire connection. Now, we handle all RFC 4254 channel messages; global requests are handled explicitly. Then, treat all other messages as a protocol error and tear the connection down instead of buffering and blocking. #### Severity Unknown #### References - [https://go.dev/issue/81317](https://go.dev/issue/81317) - [https://go.dev/cl/826524](https://go.dev/cl/826524) - [https://groups.google.com/g/golang-announce/c/1y3fb2np35U](https://groups.google.com/g/golang-announce/c/1y3fb2np35U) This data is provided by [OSV](https://osv.dev/vulnerability/GO-2026-6355) and the [Go Vulnerability Database](https://github.com/golang/vulndb) ([CC-BY 4.0](https://github.com/golang/vulndb#license)).
