CVE-2026-80804 xfs: restore nofs context unconditionally in xfs_trans_roll

In the Linux kernel, the following vulnerability has been resolved: xfs: restore nofs context unconditionally in xfstransroll When xfstranscommit fails in xfstransroll, the NOFS context is cleared but only restored in the success path. This leaves the error path without nofs protection, causing a...

SUSE CVE-2026-56855

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 connectio...

SUSE CVE-2026-78662

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,...
