In the Linux kernel, the following vulnerability has been resolved: Bluetooth: vhci: Prevent use-after-free by removing debugfs files early Move the creation of debugfs files into a dedicated function, and ensure they are explicitly removed during vhcirelease(), before associated data structures are freed. Previously, debugfs files such as "forcesuspend", "forcewakeup", and others were created under hdev->debugfs but not removed in vhcirelease(). Since vhcirelease() frees the backing vhcidata structure, any access to these files after release would result in use-after-free errors. Although hdev->debugfs is later freed in hcireleasedev(), user can access files after vhci_data is freed but before hdev->debugfs is released.
