CVE-2010-4242

Linux Kernel 2.6.36 - Denial of Service via HCI UART Driver NULL Pointer Dereference

Title source: llm

Description

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.
