Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A use-after-free issue exists in the Bluetooth component of the Linux kernel, specifically within the
btusb disconnect() function. The issue occurs because data associated with a Bluetooth interface is freed by usb driver release interface(), and then subsequently accessed, leading to a slab-use-after-free read. The fix involves reordering the cleanup process to access the btusb data before it is freed.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
