CVE-2026-64334

Published Jul 25, 2026 EPSS 0.18% (7th pctl)

Overview

CVE-2026-64334 is a known-severity vulnerability. It was published on July 25, 2026.

Technical Description

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

USB: serial: digi_acceleport: fix hard lockup on disconnect

If submitting the OOB write urb fails persistently (e.g if the device is

being disconnected) the driver would loop indefinitely with interrupts

disabled.

Check for urb submission errors when sending OOB commands to avoid

hanging if, for example, open(), set_termios() or close() races with a

physical disconnect.

This is issue was flagged by Sashiko when reviewing an unrelated change

to the driver.

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.
