{"id":"CVE-2026-43047","summary":"HID: multitouch: Check to ensure report responses match the request","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nHID: multitouch: Check to ensure report responses match the request\n\nIt is possible for a malicious (or clumsy) device to respond to a\nspecific report's feature request using a completely different report\nID.  This can cause confusion in the HID core resulting in nasty\nside-effects such as OOB writes.\n\nAdd a check to ensure that the report ID in the response, matches the\none that was requested.  If it doesn't, omit reporting the raw event and\nreturn early.","modified":"2026-10-28T02:30:43.190568666Z","published":"2026-05-01T14:15:42.562Z","related":["SUSE-SU-2026:23066-1","SUSE-SU-2026:23068-1","SUSE-SU-2026:23193-1","SUSE-SU-2026:23194-1","SUSE-SU-2026:23221-1","SUSE-SU-2026:23231-1","SUSE-SU-2026:23237-1","SUSE-SU-2026:23241-1","SUSE-SU-2026:23244-1","SUSE-SU-2026:2914-1","SUSE-SU-2026:3130-1","SUSE-SU-2026:3166-1","openSUSE-SU-2026:21555-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43047.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2edc92f89eee328b5be5706b5d431bf90669e9c0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/516da3f25cfe18643835af1cf09b0e9ffc36c383"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6a4acd3e86fe5584050c213d95147eba33856033"},{"type":"WEB","url":"https://git.kernel.org/stable/c/74c6015375d8b9bc1b1eb79f20636c8e894bcad7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7f66fdbc077faed3b52519228d21d81979e92249"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a61163daf8a90b4a7ef154d5fc9c525f665734e3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c7a27bb4d0f6573ca0f9c7ef0b63291486239190"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e716edafedad4952fe3a4a273d2e039a84e8681a"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43047.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43047"},{"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":"6d4f5440a3a2bb2e9d0d582bbf98234e9e9bb095"},{"fixed":"516da3f25cfe18643835af1cf09b0e9ffc36c383"},{"fixed":"a61163daf8a90b4a7ef154d5fc9c525f665734e3"},{"fixed":"74c6015375d8b9bc1b1eb79f20636c8e894bcad7"},{"fixed":"c7a27bb4d0f6573ca0f9c7ef0b63291486239190"},{"fixed":"6a4acd3e86fe5584050c213d95147eba33856033"},{"fixed":"7f66fdbc077faed3b52519228d21d81979e92249"},{"fixed":"2edc92f89eee328b5be5706b5d431bf90669e9c0"},{"fixed":"e716edafedad4952fe3a4a273d2e039a84e8681a"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4.3.6"},{"fixed":"4.4"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"fee906f035f0bd18ff12d84d58766c44a2ab0918"}]}],"versions":["v4.3.6"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43047.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.4.0"},{"fixed":"5.10.253"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.203"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.168"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.134"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.81"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.22"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.12"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43047.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
