What to do
AI-suggested
A fix has been implemented in the Linux kernel to address this issue. Users should update their Linux kernel to a version that includes this patch to mitigate the vulnerability. Since this is a kernel-level issue, applying the official kernel update is the recommended remediation.
Description
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.
Impact
The vulnerability could lead to use-after-free conditions in kernel space, which may cause system instability or potential escalation of privileges if exploited. However, no known exploits are reported in the wild at this time.
