Prevent DoS on deadlocked undecided channel in golang.org/x/crypto/ssh

CVE-2026-78662 / GO-2026-6354

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

Prevent DoS on deadlocked established channel in golang.org/x/crypto/ssh

CVE-2026-56855 / 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
