CVE-2026-45969

Local system crash via unchecked force-feedback initialization

Published May 27, 2026 · Updated May 27, 2026

Improper error handling in the Linux kernel PlayStation HID driver allows local users to crash the system through force-feedback effects. ps_gamepad_create() ignores a failed input_ff_create_memless() call and continues device registration instead of returning the error. Exploitation requires local low-privileged access, CONFIG_PLAYSTATION_FF, a supported controller path, and a force-feedback initialization failure; the bounded consequence is a kernel crash.
