The attacker needs local control of an assigned VF (guest VM or VF-owning container), so this is local reachability rather than network or adjacent.\nAC:L - The attacker fully controls every input \u2014 `num_tc` and per-TC `count` via ENABLE_CHANNELS, then `num_queue_pairs` and the qpair array via CONFIG_VSI_QUEUES \u2014 so shrinking `num_tc` to leave stale `ch[]` entries and then walking `idx` into them is deterministic on the first attempt with no memory grooming or race. The only precondition, spoofchk disabled, is inherent to any ADq-enabled SR-IOV deployment and is a standard runtime configuration.\nPR:L - The attacker only needs to drive the VF\u0027s admin queue \u2014 kernel/root inside the assigned guest, or possession of the VFIO device \u2014 which is a low-privileged position relative to the host PF driver under attack. No privileges of any kind on the host are required.\nUI:N - The malicious VF sends the virtchnl message sequence entirely on its own initiative. No host administrator or other user action is needed at any stage.\nS:C - The attacking VF sits in a guest VM (or VF-assigned container) while the stale-index read and the resulting hardware queue-context programming occur in the host PF driver\u0027s security authority. The corrupted resources \u2014 HMC LAN Tx/Rx contexts and QTX_CTL bindings of VSIs belonging to the PF or to other VFs \u2014 are outside the attacker\u0027s scope, crossing the guest/host and inter-tenant SR-IOV boundary.\nC:H - Using a stale `ch[idx].vsi_id`, the VF resolves and reprograms the Rx queue context of a VSI it does not own, setting `rx_ctx.base` from its own `dma_ring_addr` so another VSI\u0027s received traffic is DMA\u0027d into attacker-designated memory \u2014 interception of host and cross-guest traffic. On pre-5.2 kernels the same defect additionally reads past the end of `vf-\u003ech[]` into adjacent `struct i40e_vf` state.\nI:H - `i40e_config_vsi_rx_queue()` performs no ownership check and `i40e_config_vsi_tx_queue()` validates only the VF-supplied `info-\u003evsi_id`, so the stale ID lets the VF clear and rewrite the LAN HMC Tx/Rx contexts of a foreign VSI\u0027s queues and issue a `QTX_CTL` write rebinding that PF queue to itself. This is attacker-controlled modification of host- and peer-owned hardware state.\nA:H - Clearing and rewriting queue contexts belonging to the PF\u0027s main VSI or another guest\u0027s VSI stalls or wedges those queues, and out-of-range `pf_queue_id` values (`I40E_QUEUE_END_OF_LIST`) drive HMC operations that trigger adapter error paths, PF/VF reset storms and loss of host networking. The VF can repeat the sequence at will, and a downed host PF takes every guest on the adapter with it."

The attacker needs local control of an assigned VF (guest VM or VF-owning container), so this is local reachability rather than network or adjacent.\\nAC:L - The attacker fully controls every input \\u2014 `num_tc` and per-TC `count` via ENABLE_CHANNELS, then `num_queue_pairs` and the qpair array via CONFIG_VSI_QUEUES \\u2014 so shrinking `num_tc` to leave stale `ch[]` entries and then walking `idx` into them is deterministic on the first attempt with no memory grooming or race. The only precondition, spoofchk disabled, is inherent to any ADq-enabled SR-IOV deployment and is a standard runtime configuration.\\nPR:L - The attacker only needs to drive the VF\u0027s admin queue \\u2014 kernel/root inside the assigned guest, or possession of the VFIO device \\u2014 which is a low-privileged position relative to the host PF driver under attack. No privileges of any kind on the host are required.\\nUI:N - The malicious VF sends the virtchnl message sequence entirely on its own initiative. No host administrator or other user action is needed at any stage.\\nS:C - The attacking VF sits in a guest VM (or VF-assigned container) while the stale-index read and the resulting hardware queue-context programming occur in the host PF driver\u0027s security authority. The corrupted resources \\u2014 HMC LAN Tx/Rx contexts and QTX_CTL bindings of VSIs belonging to the PF or to other VFs \\u2014 are outside the attacker\u0027s scope, crossing the guest/host and inter-tenant SR-IOV boundary.\\nC:H - Using a stale `ch[idx].vsi_id`, the VF resolves and reprograms the Rx queue context of a VSI it does not own, setting `rx_ctx.base` from its own `dma_ring_addr` so another VSI\u0027s received traffic is DMA\u0027d into attacker-designated memory \\u2014 interception of host and cross-guest traffic. On pre-5.2 kernels the same defect additionally reads past the end of `vf-\u003ech[]` into adjacent `struct i40e_vf` state.\\nI:H - `i40e_config_vsi_rx_queue()` performs no ownership check and `i40e_config_vsi_tx_queue()` validates only the VF-supplied `info-\u003evsi_id`, so the stale ID lets the VF clear and rewrite the LAN HMC Tx/Rx contexts of a foreign VSI\u0027s queues and issue a `QTX_CTL` write rebinding that PF queue to itself. This is attacker-controlled modification of host- and peer-owned hardware state.\\nA:H - Clearing and rewriting queue contexts belonging to the PF\u0027s main VSI or another guest\u0027s VSI stalls or wedges those queues, and out-of-range `pf_queue_id` values (`I40E_QUEUE_END_OF_LIST`) drive HMC operations that trigger adapter error paths, PF/VF reset storms and loss of host networking. The VF can repeat the sequence at will, and a downed host PF takes every guest on the adapter with it.\"}]}], \"affected\": [{\"repo\":
