 Port is enabled, queue_id != 0, in qom_list 2) Port gets disabled -> team_port_disable() ->
 team_queue_override_port_del() -> del (removed from list) 3) Port is disabled, queue_id != 0, not in any
 list 4) Priority changes -> team_queue_override_port_prio_changed() -> checks: port disabled && queue_id
 != 0 -> calls del - hits the BUG as it is removed already To fix this, change the check in
 team_queue_override_port_prio_changed() so it returns early if port is not enabled. (CVE-2025-71091)

Solution

Update the linux library and its related packages to version 6.1.162-1 or later.
