{"id":"CVE-2026-43140","summary":"HID: magicmouse: Do not crash on missing msc-\u003einput","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nHID: magicmouse: Do not crash on missing msc-\u003einput\n\nFake USB devices can send their own report descriptors for which the\ninput_mapping() hook does not get called.  In this case, msc-\u003einput stays NULL,\nleading to a crash at a later time.\n\nDetect this condition in the input_configured() hook and reject the device.\n\nThis is not supposed to happen with actual magic mouse devices, but can be\nprovoked by imposing as a magic mouse USB device.","modified":"2026-06-19T08:29:27.689867727Z","published":"2026-05-06T11:27:25.536Z","related":["SUSE-SU-2026:2450-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43140.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/165912d4321c692321c02793068d30700b4e0f1a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/17abd396548035fbd6179ee1a431bd75d49676a7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/243e1165eb03aca97d87aafa9c3130593837a1c2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/36c83c1329dd881f290f7df2feadfb9a21775108"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5bbe266272d86c0657e8253600f3d5b74fb7b2ae"},{"type":"WEB","url":"https://git.kernel.org/stable/c/922bd3e498a4b8e445def6e6ffea2ad3682ad516"},{"type":"WEB","url":"https://git.kernel.org/stable/c/db5ba06e7af9325519a03e52fccf4a9e7c1fd9b2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f6a3860241fbb556fd72332fa31c5e787004413b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43140.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43140"},{"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":"64eb105d7f92fa48798106ac0d8bf17668eb2524"},{"fixed":"db5ba06e7af9325519a03e52fccf4a9e7c1fd9b2"},{"fixed":"165912d4321c692321c02793068d30700b4e0f1a"},{"fixed":"f6a3860241fbb556fd72332fa31c5e787004413b"},{"fixed":"243e1165eb03aca97d87aafa9c3130593837a1c2"},{"fixed":"922bd3e498a4b8e445def6e6ffea2ad3682ad516"},{"fixed":"5bbe266272d86c0657e8253600f3d5b74fb7b2ae"},{"fixed":"36c83c1329dd881f290f7df2feadfb9a21775108"},{"fixed":"17abd396548035fbd6179ee1a431bd75d49676a7"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-43140.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.37"},{"fixed":"5.10.252"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.202"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.165"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.128"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.75"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-43140.json"}}],"schema_version":"1.7.5"}
