A local attacker could exploit this vulnerability by providing a specially crafted HID descriptor. This malicious descriptor could cause the `sensor_hub_get_feature()` function to write data beyond the intended memory buffer. This out-of-bounds write could lead to a system crash (denial of service) or potentially allow for arbitrary code execution, compromising the system's integrity.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Red Hat OpenShift Container Platform 4 · no fix planned: Red Hat OpenShift Container Platform 4 · updated 2026-09-16 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-89729.json)\n\n**kernel: HID: sensor-hub: Fix out-of-bounds write in sensor_hub_get_feature** — rated Moderate by Red Hat.
