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.","published_at":"2026-06-24T16:30:10.930000Z","last_modified_at":null,"cvss_v3_score":7.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":null,"nvd_references":["https://git.kernel.org/stable/c/3128b294b426533c8d9162187446d93a8a160359","https://git.kernel.org/stable/c/acbf45bd584d924b320bee2a7fe2a26f64904d95","https://git.kernel.org/stable/c/866d3d9b87751b1944168fd82615505e0c0fd6cf","https://git.kernel.org/stable/c/183128da0406b1c10e6f60b7b9fe70788b9c8c1d","https://git.kernel.org/stable/c/7bad93e99737e4a5c0c14ac50c05152cf4e28022","https://git.kernel.org/stable/c/ea690b3b6e58ae00979af8195b4cc24df466b65e","https://git.kernel.org/stable/c/1921f91298d1388a0bb9db8f83800c998b649cb3"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-28T17:55:28.590503Z","updated_at":"2026-06-28T23:30:50.753831Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack
