Description

An issue was discovered in the Linux kernel before 5.0.5. There is a use-after-free issue when hci_uart_register_dev() fails in hci_uart_set_proto() in drivers/bluetooth/hci_ldisc.c. A flaw was found in the Linux kernel's implementation of the HCI UART driver. A local attacker with access permissions to the Bluetooth device can issue an ioctl, which triggers the hci_uart_set_proto() function in drivers/bluetooth/hci_ldisc.c. The flaw in this function can cause memory corruption or a denial of service because of a use-after-free issue when the hci_uart_register_dev() fails.
