Vulnerability Name:

CVE-2010-4242 (CCN-64617)

Assigned:2010-10-08
Published:2010-10-08
Updated:2018-10-10
Summary:The hci_uart_tty_open function in the HCI UART driver (drivers/bluetooth/hci_ldisc.c) in the Linux kernel 2.6.36, and possibly other versions, does not verify whether the tty has a write operation, which allows local users to cause a denial of service (NULL pointer dereference) via vectors related to the Bluetooth driver.
