SB2026050211 - Use-after-free in Linux kernel hid driver

Description

This security bulletin contains information about 1 vulnerability.

1) Use-after-free (CVE-ID: CVE-2026-43049)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to a use-after-free in the logitech-hidpp force feedback initialization path when probing the Logitech G920 Driving Force Racing Wheel for Xbox One and userspace continues to access sysfs or /dev/input references after initialization failure. A local user can trigger force feedback initialization failure and use dangling references to cause a denial of service.

The issue occurs if force feedback initialization fails before the userspace infrastructure has been torn down.

Remediation

Install update from vendor's website.
