If registration of an input device fails during configuration, the driver frees the device memory while communication channels are already active, leaving a dangling reference. An attacker capable of attaching a malicious device or sending crafted input reports can trigger a use-after-free condition during this failure window. This flaw primarily results in a Denial of Service (DoS) through a kernel crash, and may potentially allow arbitrary code execution.\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 2026-10-24 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-98501.json)\n\n**kernel: HID: alps: fix use-after-free on input2 registration failure** — rated Moderate by Red Hat.
