CVE-2010-4242

Priority
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.
Ubuntu-Description
Alan Cox discovered that the HCI UART driver did not correctly check if a
write operation was available. If the mmap_min-addr sysctl was changed from
the Ubuntu default to a value of 0, a local attacker could exploit this
flaw to gain root privileges.
