Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
ice: Add netif_device_attach/detach into PF reset flow
Ethtool callbacks can be executed while reset is in progress and try to access deleted resources, e.g. getting coalesce settings can result in a NULL pointer dereference seen below.
Reproduction steps:
Once the driver is fully initialized, trigger reset:
# echo 1 > /sys/class/net/
BUG: kernel NULL pointer dereference, address: 0000000000000020

Call Trace:
Calling netif_device_detach() before reset makes the net core not call the driver when ethtool command is issued, the attempt to execute an ethtool command during reset will result in the following message:
netlink error: No such device
instead of NULL pointer dereference. Once reset is done and ice_rebuild() is executing, the netif_device_attach() is called to allow for ethtool operations to occur again in a safe manner.
