  "details": "In the Linux kernel, the following vulnerability has been resolved:  ksmbd: unset conn-\u003ebinding on failed binding request  When a multichannel SMB2_SESSION_SETUP request with SMB2_SESSION_REQ_FLAG_BINDING fails ksmbd sets conn-\u003ebinding = true but never clears it on the error path. This leaves the connection in a binding state where all subsequent ksmbd_session_lookup_all() calls fall back to the global sessions table. This fix it by clearing conn-\u003ebinding = false in the error path.",
