Recommendation: Monitor — no exploitation signal at the moment.
In the Linux kernel, the following vulnerability has been resolved:
i40e: fix validation of VF state in get resources
VF state I40E_VF_STATE_ACTIVE is not the only state in which
VF is actually active so it should not be used to determine
if a VF is allowed to obtain resources.
Use I40E_VF_STATE_RESOURCES_LOADED that is set only in
i40e_vc_get_vf_resources_msg() and cleared during reset.
