Subject: [PATCH spice 1/6] server: guest_set_client_capabilities: protect
|
|
against NULL worker->display_channel
|
|
|
|
Reported-by: Michal Luscon <mluscon@redhat.com>

Found by a Coverity scan:
|
|
in handle_dev_start -
|
|
Checking "worker->display_channel" implies that "worker->display_channel"
|
|
might be NULL.
|
|
Passing "worker" to function "guest_set_client_capabilities"
|
|
in guest_set_client_capabilities -
|
|
Directly dereferencing parameter "worker->display_channel"
