Description

This security bulletin contains information about 1 vulnerability.


1) Improper locking (CVE-ID: CVE-2026-53037)

CWE-ID: CWE-667 - Improper Locking

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


The vulnerability allows an attacker with physical access to cause a denial of service.

The vulnerability exists due to improper resource management in hid_post_reset() when processing a reset of a crafted USB device that includes both HID and storage or UAS components. An attacker with physical access can connect a crafted USB device to trigger a deadlock and cause a denial of service.

The issue occurs because the components can be reset only together, placing the affected code in block I/O error handling.
