Affected: Linux

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/<interface>/device/reset when reset is in progress try to get coalesce settings using ethtool: # ethtool -c <interface>
