In the Linux kernel, the following vulnerability has been resolved:
igb: Fix NULL pointer dereference in ethtool loopback test
The igb driver currently causes a NULL pointer dereference when executing
the ethtool loopback test. This occurs because there is no associated
q_vector for the test ring when it is set up, as interrupts are typically
not added to the test rings.
Since commit 5ef44b3cb43b removed the napi_id assignment in
__xdp_rxq_info_reg(), there is no longer a need to pass a napi_id to it.
Therefore, simply use 0 as the last parameter.
