"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnfc: nci: fix uninit-value in the RF discover/activated NTF handlers\n\nnci_rf_discover_ntf_packet() and nci_rf_intf_activated_ntf_packet() each\nparse a notification into an on-stack struct (nci_rf_discover_ntf /\nnci_rf_intf_activated_ntf) that is not initialised. The RF\ntechnology-specific parameters are only extracted when\nrf_tech_specific_params_len is non-zero, so a notification that reports a\nzero length leaves the rf_tech_specific_params union uninitialised - and\nboth handlers then pass it to nci_add_new_protocol(), which reads it:\n\n - discover: nci_add_new_target() -> nci_add_new_protocol();\n - activated: nci_target_auto_activated() -> nci_add_new_protocol().\n\nnci_add_new_protocol() uses nfca_poll->nfcid1_len as both a branch\ncondition and a memcpy() length and copies nfcid1/sens_res/sel_res into\nndev->targets, which is later exposed to user space via NFC_CMD_GET_TARGET.\n\n BUG: KMSAN: uninit-value in nci_add_new_protocol+0x624/0x6c0\n nci_add_new_protocol+0x624/0x6c0\n nci_ntf_packet+0x25b2/0x3c30\n nci_rx_work+0x318/0x5d0\n process_scheduled_works+0x84b/0x17a0\n worker_thread+0xc10/0x11b0\n kthread+0x376/0x500\n Local variable ntf.i created at:\n nci_ntf_packet+0xbc2/0x3c30\n\nZero-initialise both on-stack notifications so the union reads back as\nzero when no technology-specific parameters are present."
