CVE-2011-1079 - Renderable Bill

Description

The bnep_sock_ioctl function in net/bluetooth/bnep/sock.c in the Linux kernel before 2.6.39 does not ensure that a certain device field ends with a ‘\0’ character which allows local users to obtain potentially sensitive information from kernel stack memory or cause a denial of service (BUG and system crash) via a BNEPCONNADD command.
