In the Linux kernel, the following vulnerability has been resolved:

bonding: Fix unnecessary warnings and logs from bond_xdp_get_xmit_slave()

syzbot reported a WARNING in bond_xdp_get_xmit_slave. To reproduce
this[1], one bond device (bond1) has xdpdrv, which increases
bpf_master_redirect_enabled_key. Another bond device (bond0) which is
unsupported by XDP but its slave (veth3) has xdpgeneric that returns
XDP_TX. This triggers WARN_ON_ONCE() from the xdp_master_redirect().
To reduce unnecessary warnings and improve log management, we need to
delete the WARN_ON_ONCE() and add ratelimit to the netdev_err().

[1] Steps to reproduce:
    # Needs tx_xdp with return XDP_TX;
    ip l add veth0 type veth peer veth1
    ip l add veth3 type veth peer veth4
    ip l add bond0 type bond mode 6 # BOND_MODE_ALB, unsupported by XDP
    ip l add bond1 type bond # BOND_MODE_ROUNDROBIN by default
    ip l set veth0 master bond1
    ip l set bond1 up
    # Increases bpf_master_redirect_enabled_key
    ip l set dev bond1 xdpdrv object tx_xdp.o section xdp_tx
    ip l set veth3 master bond0
    ip l set bond0 up
    ip l set veth4 up
    # Triggers WARN_ON_ONCE() from the xdp_master_redirect()
    ip l set veth3 xdpgeneric object tx_xdp.o section xdp_tx
