Full vulnerability record from the local CVENow database.
Description
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.
