{"id":"CVE-2026-80771","summary":"HID: nintendo: register input device after capabilities are set","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nHID: nintendo: register input device after capabilities are set\n\ninput_register_device() exposes the device to userspace immediately.\nIn joycon_input_create() it was called before joycon_config_rumble()\nconfigures the FF_RUMBLE capability and the memless force-feedback\ndevice, so a concurrent EVIOCSFF could dereference a NULL dev-\u003eff.\n\nRegistering early also means the initial udev event lacks button and\naxis information, which can make input managers ignore the device.\n\nMove input_register_device() to the end of joycon_input_create(), after\nall capabilities, the IMU input device and the force-feedback callbacks\nhave been configured.","modified":"2026-09-06T03:46:44.861464038Z","published":"2026-09-04T15:12:43.246Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80771.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/268679f501386ad46405d42c2bcf89384cb5e256"},{"type":"WEB","url":"https://git.kernel.org/stable/c/27dc4b8eadac73b3c3cc526c8547d8b4ae8528be"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3288bec1a21d582b504344380139cdc0e88ebe4d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a9fc7547f911ada09da33c5e204e5acda38e765a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d723bc1fe2e72b9252234e94c11af644ec477bf7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80771.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80771"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"2af16c1f846bd60240745bbd3afa13d5f040c61a"},{"fixed":"3288bec1a21d582b504344380139cdc0e88ebe4d"},{"fixed":"268679f501386ad46405d42c2bcf89384cb5e256"},{"fixed":"a9fc7547f911ada09da33c5e204e5acda38e765a"},{"fixed":"27dc4b8eadac73b3c3cc526c8547d8b4ae8528be"},{"fixed":"d723bc1fe2e72b9252234e94c11af644ec477bf7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80771.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.12.106"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.47"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.11"}]},{"type":"ECOSYSTEM","events":[{"introduced":"7.2.0"},{"fixed":"7.2.1"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80771.json"}}],"schema_version":"1.9.0"}
