CVE-2013-0349

Published: 26 February 2013

The hidp_setup_hid function in net/bluetooth/hidp/core.c in the Linux kernel before 3.7.6 does not properly copy a certain name field, which allows local users to obtain sensitive information from kernel memory by setting a long name and making an HIDPCONNADD ioctl call.

From the Ubuntu security team

An information leak was discovered in the Linux kernel's Bluetooth stack when HIDP (Human Interface Device Protocol) support is enabled. A local unprivileged user could exploit this flaw to cause an information leak from the kernel.

there is NO HCONFING_BT, it is CONFIG_BT
O,P,Q,R:
CONFIG_BT=m
CONFIG_BT_HIDP=m
luicd:
CONFIG_BT=m/y on all arch except: armel and sparc
CONFIG_BT_HIDP=m
