A local attacker can exploit a heap buffer overflow by providing a specially crafted report through a `hidraw SET_REPORT/SET_FEATURE ioctl`. This allows the attacker to overflow a buffer with controlled length and content, potentially leading to memory corruption or denial of service.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Important · 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 2026-09-14 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-89620.json)\n\n**kernel: HID: intel-thc-hid: intel-quickspi: validate report size before copy** — rated Important by Red Hat.
