CVE-2026-64345

Published Jul 25, 2026 EPSS 0.17% (7th pctl)

Overview

CVE-2026-64345 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: gadget: f_printer: take kref only for successful open

printer_open() returns -EBUSY when the character device is already

open, but it increments dev->kref regardless of the return value. VFS

does not call ->release() for a failed open, so every rejected second

open permanently leaks one reference.

Move kref_get() into the successful-open branch.

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.
