Description
A use-after-free vulnerability was found in the Linux kernel's Bluetooth HCI socket implementation. A race condition between socket bind and write operations allows mgmt_pending to free a command structure while write_iter is still attempting to send it, resulting in use-after-free when the freed memory is accessed.
