Description Prasad Pandit 2013-03-16 17:53:55 UTC

Linux kernel built with Bluetooth networking with RFCOMM protocol support
is vulnerable to information leakage flaws. These occur while calling
getsockname, getsockopt(BT_SECURITY), and ioctl(RFCOMMGETDEVLIST) routines.

A user/program could use this flaw to leak kernel memory bytes.
