{"id":"CVE-2026-93826","summary":"HID: hidpp: fix potential UAF in hidpp_connect_event()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nHID: hidpp: fix potential UAF in hidpp_connect_event()\n\nIf input_register_device() fails, we call input_free_device(), but keep\nstale pointer to the old device in hidpp-\u003einput, which could potentially\nlead to UAF. Fix that by resetting it to NULL before returning from\nhidpp_connect_event().","modified":"2026-09-26T03:48:26.837829036Z","published":"2026-09-24T16:03:04.711Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93826.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3303398cc2aa255ba251650a30024e11d48ea6c3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3b8b2e58b078cd30e121401535541bb8a6d57133"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6df6b1f2c49678211f65647c300bc51dda02893b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93826.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93826"},{"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":"c39e3d5fc9dd3e16c6f59dd94d827540040de66d"},{"fixed":"3b8b2e58b078cd30e121401535541bb8a6d57133"},{"fixed":"3303398cc2aa255ba251650a30024e11d48ea6c3"},{"fixed":"6df6b1f2c49678211f65647c300bc51dda02893b"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93826.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.19.0"},{"fixed":"6.12.111"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.53"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93826.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
