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.

A flaw was found in the Linux kernel's Bluetooth USB (btusb) driver. This vulnerability occurs during the Marvell Out-Of-Band (OOB) wakeup configuration when a probe failure happens. An attacker could potentially exploit a use-after-free condition in the completion callback, which may lead to system instability, denial of service, or potentially arbitrary code execution.
