Title
ice: Fix NULL pointer dereference in ice_vsi_set_napi_queues
Summary
In the Linux kernel, the following vulnerability has been resolved: ice: Fix NULL pointer dereference in ice_vsi_set_napi_queues Add NULL pointer checks in ice_vsi_set_napi_queues() to prevent crashes during resume from suspend when rings[q_idx]->q_vector is NULL. Tested adaptor: 60:00.0 Ethernet controller [0200]: Intel Corporation Ethernet Controller E810-XXV for SFP [8086:159b] (rev 02) Subsystem: Intel Corporation Ethernet Network Adapter E810-XXV-2 [8086:4003] SR-IOV state: both disabled and enabled can reproduce this issue. kernel version: v6.18 Reproduce steps: Boot up and execute suspend like systemctl suspend or rtcwake.
