CVE-2025-39875

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