Use-after-free in Linux kernel - CVE-2026-90329

Vulnerability identifier: #VU151149

CSH Severity: Low

CVSS v4: 0 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-90329

CWE-ID: CWE-416

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to trigger a use-after-free.

The vulnerability exists due to a use-after-free in HID failed-probe cleanup when a HID report callback runs concurrently with a failed device probe. A local user can cause a HID report to be processed while a device probe fails to trigger a use-after-free.
