Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A vulnerability in the Linux kernel's Bluetooth functionality has been resolved. The issue was related to the Mediatek btusb code, which did not properly claim the device lock when calling
usb driver claim interface() from certain paths. This led to errors such as "Failed to claim iso interface" and, in some cases, NULL pointer dereferences. The fix involves adding locks for usb driver claim interface() to prevent these errors.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
