Overview

CVE-2026-23082 is a medium-severity vulnerability. It was published on February 4, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

can: gs_usb: gs_usb_receive_bulk_callback(): unanchor URL on usb_submit_urb() error

In commit 7352e1d5932a ("can: gs_usb: gs_usb_receive_bulk_callback(): fix

URB memory leak"), the URB was re-anchored before usb_submit_urb() in

gs_usb_receive_bulk_callback() to prevent a leak of this URB during

cleanup.

However, this patch did not take into account that usb_submit_urb() could

fail. The URB remains anchored and

usb_kill_anchored_urbs(&parent->rx_submitted) in gs_can_close() loops

infinitely since the anchor list never becomes empty.

To fix the bug, unanchor the URB when an usb_submit_urb() error occurs,

also print an info message.

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.
