Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
idpf: convert control queue mutex to a spinlock
With VIRTCHNL2_CAP_MACFILTER enabled, the following warning is generated
on module load:

The sequence is as follows:
rtnl_newlink()->
__dev_change_flags()->
__dev_open()->
dev_set_rx_mode() - > # disables BH and grabs "dev->addr_list_lock"
idpf_set_rx_mode() -> # proceed only if VIRTCHNL2_CAP_MACFILTER is ON
__dev_uc_sync() ->
idpf_add_mac_filter ->
idpf_add_del_mac_filters ->
idpf_send_mb_msg() ->
idpf_mb_clean() ->
idpf_ctlq_clean_sq() # mutex_lock(cq_lock)
Fix by converting cq_lock to a spinlock. All operations under the new
lock are safe except freeing the DMA memory, which may use vunmap(). Fix
by requesting a contiguous physical memory for the DMA mapping.
