Description Prasad Pandit 2013-04-24 10:24:30 UTC

Linux kernel built with the Near Field Communication(CONFIG_NFC) subsystem
along with the Logical Link Control Protocol(CONFIG_NFC_LLCP) support is
vulnerable to an information leakage flaw. It occurs while receiving messages
via recvmsg(2) call.

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

Upstream fix:
