- Summary
- idpf: fix aux device unplugging when rdma is not supported by vport
- Details
-
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.
