CVE-2024-53088

VF networking disruption via i40e filter use-after-free

Published Nov 19, 2024 · Updated Aug 5, 2026

Race condition in the Linux i40e driver allows local users to corrupt and leak MAC/VLAN filter entries through concurrent VF changes. The filter synchronization path dereferences an entry after a concurrent MAC-setting operation frees it while a port-VLAN operation retains it on a temporary add list. Exploitation requires multiple SR-IOV virtual functions, host network-administration privileges, and sustained parallel MAC and port-VLAN changes; corruption can prevent RX-filter installation and disrupt VF networking.
