Technical description

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

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

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.

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.
