Description Prasad Pandit 2014-01-15 14:10:27 UTC

Linux kernel built with the YAM modem driver for AX.25(CONFIG_YAM) is
vulnerable to an information leakage flaw. It could occur while doing an
ioctl(SIOCYAMGCFG) call.

A user/program with CAP_NET_ADMIN privileges could use this flaw to leak (four)kernel memory bytes.
