A use-after-free vulnerability exists where the `enable_sensor` sysfs attribute can be accessed either before its associated memory is properly initialized or after it has been freed during device removal. A local attacker could exploit this condition to cause a system crash (denial of service) or potentially achieve arbitrary code execution due to memory corruption.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat OpenShift Container Platform 4 · no fix planned: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, … · updated 2026-10-25 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-80767.json)\n\n**kernel: HID: sensor: custom: Fix use-after-free in enable_sensor** — rated Moderate by Red Hat.
