      "title": "net, bpf: fix null-ptr-deref in xdp_master_redirect() for down master",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet, bpf: fix null-ptr-deref in xdp_master_redirect() for down master\n\nsyzkaller reported a kernel panic in bond_rr_gen_slave_id() reached via\nxdp_master_redirect(). Full decoded trace:\n\n  https://syzkaller.appspot.com/bug?extid=80e046b8da2820b6ba73\n\nbond_rr_gen_slave_id() dereferences bond->rr_tx_counter, a per-CPU\ncounter that bonding only allocates in bond_open() when the mode is\nround-robin. If the bond device was never brought up, rr_tx_counter\nstays NULL.\n\nThe XDP redirect path can still reach that code on a bond that was\nnever opened: bpf_master_redirect_enabled_key is a global static key,\nso as soon as any bond device has native XDP attached, the\nXDP_TX -> xdp_master_redirect() interception is enabled for every\nslave system-wide. The path xdp_master_redirect() ->\nbond_xdp_get_xmit_slave() -> bond_xdp_xmit_roundrobin_slave_get() ->\nbond_rr_gen_slave_id() then runs against a bond that has no\nrr_tx_counter and crashes.\n\nFix this in the generic xdp_master_redirect() by refusing to call into\nthe master's ->ndo_xdp_get_xmit_slave() when the master device is not\nup. IFF_UP is only set after ->ndo_open() has successfully returned,\nso this reliably excludes masters whose XDP state has not been fully\ninitialized. Drop the frame with XDP_ABORTED so the exception is\nvisible via trace_xdp_exception() rather than silently falling through.\nThis is not specific to bonding: any current or future master that\ndefers XDP state allocation to ->ndo_open() is protected.",
