Description OSIDB Bzimport 2025-10-15 08:01:44 UTC 
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.
