  - In the Linux kernel, the following vulnerability has been resolved: ice: Fix race condition during
    interface enslave Commit 5dbbbd01cbba83 (ice: Avoid RTNL lock when re-creating auxiliary device) changes
    a process of re-creation of aux device so ice_plug_aux_dev() is called from ice_service_task() context.
    This unfortunately opens a race window that can result in dead-lock when interface has left LAG and
    immediately enters LAG again. Reproducer: ``` #!/bin/sh ip link add lag0 type bond mode 1 miimon 100 ip
    link set lag0 for n in {1..10}; do echo Cycle: $n ip link set ens7f0 master lag0 sleep 1 ip link set
    ens7f0 nomaster done ``` This results in: [20976.208697] Workqueue: ice ice_service_task [ice]

    entry_SYSCALL_64_after_hwframe+0x65/0xca 1. Command 'ip link ... set nomaster' causes that
    ice_plug_aux_dev() is called from ice_service_task() context, aux device is created and associated
    device->lock is taken. 2. Command 'ip link ... set master...' calls ice's notifier under RTNL lock and
    that notifier calls ice_unplug_aux_dev(). That function tries to take aux device->lock but this is already
    taken by ice_plug_aux_dev() in step 1 3. Later ice_plug_aux_dev() tries to take RTNL lock but this is
    already taken in step 2 4. Dead-lock The patch fixes this issue by following changes: - Bit
    ICE_FLAG_PLUG_AUX_DEV is kept to be set during ice_plug_aux_dev() call in ice_service_task() - The bit is
    checked in ice_clear_rdma_cap() and only if it is not set then ice_unplug_aux_dev() is called. If it is
    set (in other words plugging of aux device was requested and ice_plug_aux_dev() is potentially running)
    then the function only clears the ---truncated--- (CVE-2022-48842)
