{"id":"CVE-2026-89619","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-89619","summary":"HID: intel-thc-hid: intel-quickspi: bound GET_REPORT response to the caller buffer","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nHID: intel-thc-hid: intel-quickspi: bound GET_REPORT response to the caller buffer\n\nquickspi_hid_raw_request() receives the caller's buffer length in len, but\nquickspi_get_report() never sees it and copies the whole device-supplied\nresponse into buf regardless:\n\n    memcpy(buf, qsdev->report_buf, qsdev->report_len);\n\nqsdev->report_len comes from the input report the touch controller returns,\nwhile buf is sized to whatever the caller asked hidraw for through\nHIDIOCGFEATURE or HIDIOCGINPUT.  A response larger than that overflows buf\nwith device-controlled content.\n\nThe intel-quicki2c sibling already passes the caller length down to\nquicki2c_get_report() and validates the response against it before the\ncopy.  Do the same here.","published":"2026-09-11T19:45:18.073Z","modified":"2026-09-14T03:46:19.424749799Z","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"6.18.50"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/035ec4a71cb8020a927c123bbe75c2f88d614986"},{"type":"WEB","url":"https://git.kernel.org/stable/c/54e0bafc0653bdf2a6c5f5f8ad8787a820d98663"},{"type":"WEB","url":"https://git.kernel.org/stable/c/72706b44b665679d7d60a488d8776a911f1a93f3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89619.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89619"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-14T03:46:19.424749799Z"}}
