Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: net, bpf: fix null-ptr-deref in
xdp_master_redirect() for down master syzkaller reported a kernel panic in bond_rr_gen_slave_id() reached
via xdp_master_redirect(). Full decoded trace:
https://syzkaller.appspot.com/bug?extid=80e046b8da2820b6ba73 bond_rr_gen_slave_id() dereferences
bond->rr_tx_counter, a per-CPU counter that bonding only allocates in bond_open() when the mode is round-
robin. If the bond device was never brought up, rr_tx_counter stays NULL. The XDP redirect path can still
reach that code on a bond that was never opened: bpf_master_redirect_enabled_key is a global static key,
so as soon as any bond device has native XDP attached, the XDP_TX -> xdp_master_redirect() interception is
enabled for every slave system-wide. The path xdp_master_redirect() -> bond_xdp_get_xmit_slave() ->
bond_xdp_xmit_roundrobin_slave_get() -> bond_rr_gen_slave_id() then runs against a bond that has no
rr_tx_counter and crashes. Fix this in the generic xdp_master_redirect() by refusing to call into the
master's ->ndo_xdp_get_xmit_slave() when the master device is not up. IFF_UP is only set after
->ndo_open() has successfully returned, so this reliably excludes masters whose XDP state has not been
fully initialized. Drop the frame with XDP_ABORTED so the exception is visible via trace_xdp_exception()
rather than silently falling through. This is not specific to bonding: any current or future master that
defers XDP state allocation to ->ndo_open() is protected. (CVE-2026-53069)
