AI-suggested
A fix is available that properly stops the device when force-feedback initialization fails after the device has started. Users should apply the official Linux kernel updates that address this issue in the affected versions. There are no vendor advisories indicating 'no action required' or that the issue is already mitigated without patching. Until patched, avoid using affected HID devices that trigger force-feedback initialization failures.
Description
A vulnerability in the Linux kernel's HID universal-pidff driver causes a use-after-free condition when force-feedback initialization fails after the device has started. This occurs because the device is not properly stopped, leaving the hidraw character device registered and accessible, which can lead to writing into freed memory. The issue affects specific Linux kernel versions and has been resolved by ensuring the device is stopped on failure paths after starting.
