The vulnerability has been resolved in the Linux kernel. Users should apply the official Linux kernel updates that include the fix for this issue.
Description
A use-after-free vulnerability in the Linux kernel's Bluetooth USB driver (btusb) was fixed. The flaw occurred when controller registration failed and sibling interfaces were not properly released, leading to potential use-after-free and double-free conditions.
