Description Prasad Pandit 2013-04-23 13:35:55 UTC

Linux kernel built with the Amateur Radio support(CONFIG_HAMRADIO) along with
the Amateur Radio AX.25 Level 2 protocol support enabled 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:
