How to fix?

Upgrade SLES:16.0.0 kernel-source to version 6.12.0-160000.27.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-source package and not the kernel-source package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

idpf: fix aux device unplugging when rdma is not supported by vport

If vport flags do not contain VIRTCHNL2_VPORT_ENABLE_RDMA, driver does not allocate vdev_info for this vport. This leads to kernel NULL pointer dereference in idpf_idc_vport_dev_down(), which references vdev_info for every vport regardless.

Check, if vdev_info was ever allocated before unplugging aux device.
