Description

An issue was discovered in drivers/bluetooth/hci_ldisc.c in the Linux kernel 6.2. In hci_uart_tty_ioctl, there is a race condition between HCIUARTSETPROTO and HCIUARTGETPROTO. HCI_UART_PROTO_SET is set before hu->proto is set. A NULL pointer dereference may occur. A NULL pointer dereference flaw was found in the Linux kernel’s Bluetooth HCI UART driver. This flaw allows a local user to crash the system.
