| Description: | The rfcomm_sock_recvmsg function in net/bluetooth/rfcomm/sock.c in the Linux kernel before 3.9-rc7 does not initialize a certain length variable, which allows local users to obtain sensitive information from kernel stack memory via a crafted recvmsg or recvfrom system call. An information leak was discovered in the Linux kernel's bluetooth rfcomm protocol support. A local user could exploit this flaw to examine potentially sensitive information from the kernel's stack memory.
