When the `hidinput_connect()` function fails to register an input device, the driver may continue to use a pointer to memory that has already been released. This use-after-free vulnerability can lead to system instability or crashes, and potentially allow a local attacker to escalate privileges or execute arbitrary code.\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-2026-80782.json)\n\n**kernel: HID: magicmouse: do not keep a stale msc->input if no input is claimed** — rated Moderate by Red Hat.
