CVE-2026-43049

/// Technical description

In the Linux kernel, the following vulnerability has been resolved:

HID: logitech-hidpp: Prevent use-after-free on force feedback initialisation failure

Presently, if the force feedback initialisation fails when probing the

Logitech G920 Driving Force Racing Wheel for Xbox One, an error number

will be returned and propagated before the userspace infrastructure

(sysfs and /dev/input) has been torn down. If userspace ignores the

errors and continues to use its references to these dangling entities, a

UAF will promptly follow.

We have 2 options; continue to return the error, but ensure that all of

the infrastructure is torn down accordingly or continue to treat this

condition as a warning by emitting the message but returning success.

It is thought that the original author's intention was to emit the

warning but keep the device functional, less the force feedback feature,

so let's go with that.

/// Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
