CVE-2010-4242

kernel: missing tty ops write function presence check in hci_uart_tty_open()

Published Jan 11, 2011 CVSS 2.0 · 4.0 Medium EPSS < 1% KEV · Not listed
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.
