{ "lang": "en", "value": "AV:A - The overflow is reached while parsing NCI RF_DISCOVER_NTF frames delivered by the NFC controller from an NFC peer/tag in RF range (nci_recv_frame → nci_rx_work → nci_ntf_packet → nci_rf_discover_ntf_packet → nci_add_new_protocol), matching established AV:A scoring for NCI bugs (CVE-2024-35915, CVE-2024-38381, CVE-2023-52502).\nAC:L - A single crafted Discover NTF (e.g. NFC-F with rf_tech_specific_params_len=0 leaving sensf_res_len uninitialized, or any path that supplies a length > array size) deterministically drives the unbounded memcpy; ~93% of random u8 lengths exceed the 18-byte field, with no race or attacker-uncontrollable precondition.\nPR:N - NFC discovery notifications are processed with no authentication from an adjacent peer while the platform NFC stack is polling, and the same parser is reachable via N_NCI without credentials; no attacker-held capability is required on the severe path.\nUI:N - Frames are handled asynchronously on nci_rx_work during normal autonomous NFC poll/discovery; no victim action such as mounting a filesystem or confirming a prompt is required.\nS:U - The out-of-bounds write corrupts kernel heap state inside struct nci_dev (targets[] and adjacent fields) within the host OS security authority, with no VM escape, IOMMU bypass, or sandbox boundary cross.\nC:H - The oversized memcpy both reads past the 18-byte source on the stack and writes past target->sensf_res into adjacent nfc_target/nci_dev heap memory, and the inflated sensf_res_len is later exported via nfc_genl_send_target netlink attributes—memory corruption with a disclosure path, scored Confidentiality High.\nI:H - This is a genuine heap out-of-bounds write of up to 255 bytes into ndev->targets[] (and past the array for late indices into n_targets and following nci_dev fields), enabling corruption of kernel NFC state and control-flow primitives per OOB-write guidance.\nA:H - Syzkaller already hit a fortify WARNING that panics under panic_on_warn, and an unbounded heap write in workqueue context reliably produces kernel oops/panic even when not fully exploited." } ] } ], "affected": [ { "product": "Linux", "vendor":
