CVE-2022-49667 is a use-after-free vulnerability in the Linux kernel bonding driver’s IEEE 802.3ad/LACP aggregation handling. In bonds containing multiple aggregation groups, an 802.3ad slave unbind can clear an aggregator even while its recorded port count is nonzero. A later slave-unbind operation can then leave slave-port entries pointing to freed aggregator memory because the slave-port list is not updated when lag_ports is NULL. The condition was observed as a use-after-free read in bond_3ad_state_machine_handler.
