Vulnerability identifier: #VU151150

CSH Severity: Low

CVSS v4: 2 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-90330

CWE-ID: CWE-401

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to cause a resource leak.

The vulnerability exists due to improper resource cleanup in hidpp_ff_init() when initializing a force-feedback device. A local user can trigger force-feedback device initialization to cause a resource leak.

The issue occurs when allocation of the HID++ force-feedback private data, effect ID array, or workqueue fails after the force-feedback device is created.
