Title

Bluetooth: btusb: fix use-after-free on marvell probe failure

Summary

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btusb: fix use-after-free on marvell probe failure Make sure to stop any TX URBs submitted during Marvell OOB wakeup configuration on later probe failures to avoid use-after-free in the completion callback. This issue was reported by Sashiko while reviewing a fix for a wakeup source leak in the btusb probe errors paths.

Vulnerability from github – Published: 2026-07-25 12:31 – Updated: 2026-07-25 12:31

Details

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

Bluetooth: btusb: fix use-after-free on marvell probe failure

Make sure to stop any TX URBs submitted during Marvell OOB wakeup configuration on later probe failures to avoid use-after-free in the completion callback.

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