Overview

CVE-2026-64601 is a high-severity vulnerability. It was published on August 6, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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:

ALSA: us144mkii: capture_urb_complete: redundant usb_anchor_urb corrupts anchor list on each resubmission

In capture_urb_complete(), usb_anchor_urb() is called on every

completion callback, but the URB is already anchored from the

initial submission in tascam_trigger_start(). Each redundant call

corrupts the anchor's doubly-linked list and inflates the URB

refcount. When usb_kill_anchored_urbs() traverses the list during

stream stop / suspend / disconnect, the corrupted list leads to

use-after-free.

Remove the redundant usb_anchor_urb() from the resubmit path.

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.
