- ice: Fix NULL pointer dereference in ice_vsi_set_napi_queues
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
ice: Fix NULL pointer dereference in icevsisetnapiqueues
Add NULL pointer checks in icevsisetnapiqueues() to prevent crashes during resume from suspend when rings[qidx]->qvector 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.

Add defensive checks for both the ring pointer and its qvector before dereferencing, allowing the system to resume successfully even when qvectors are unmapped.
