# CVE-2026-64471

> 3.1 LOW

## Beschreibung

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

Bluetooth: btusb: fix use-after-free on registration failure

Make sure to release the sibling interfaces in case controller
registration fails to avoid use-after-free and double-free when they are
eventually disconnected.

This issue was reported by Sashiko while reviewing a fix for a wakeup
source leak in the btusb probe errors paths.
