This vulnerability allows a malicious Human Interface Device (HID) to send an oversized report, which is then copied into a buffer without proper size validation. This leads to a buffer overflow, a type of memory corruption, which could potentially allow an attacker to execute arbitrary code or cause a system crash (denial of service).\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 9, Red Hat OpenShift Container Platform 4 · no fix planned: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 9, Red Hat OpenShift Container Platform 4 · updated 2026-09-18 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-89619.json)\n\n**kernel: HID: intel-thc-hid: intel-quickspi: bound GET_REPORT response to the caller buffer** — rated Moderate by Red Hat.
