Summary
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: af_bluetooth: Fix deadlock Attemting to do sock_lock on .recvmsg may cause a deadlock as shown bellow, so instead of using sock_sock this uses sk_receive_queue.lock on bt_sock_ioctl to avoid the UAF: INFO: task kworker/u9:1:121 blocked for more than 30 seconds.
