A use-after-free vulnerability in the Linux kernel Bluetooth subsystem (hci_core) was resolved. The issue arises because ACL scheduling and channel deletion are not properly serialized, allowing a channel to be freed while still in use. This leads to a use-after-free condition detected by KASAN. The fix involves holding a device mutex to serialize channel selection, transmission, and teardown, preventing concurrent access to freed channels.
