Description
The llcp_sock_recvmsg function in net/nfc/llcp/sock.c in the Linux kernel before 3.9-rc7 does not initialize a certain length variable and a certain data structure, which allows local users to obtain sensitive information from kernel stack memory via a crafted recvmsg or recvfrom system call.
