The Linux kernel before 2.6.31-rc7 does not initialize certain data
structures within getname functions, which allows local users to read the
contents of some kernel memory locations by calling getsockname on (1) an
AF_APPLETALK socket, related to the atalk_getname function in
net/appletalk/ddp.c; (2) an AF_IRDA socket, related to the irda_getname
function in net/irda/af_irda.c; (3) an AF_ECONET socket, related to the
econet_getname function in net/econet/af_econet.c; (4) an AF_NETROM socket,
related to the nr_getname function in net/netrom/af_netrom.c; (5) an
AF_ROSE socket, related to the rose_getname function in net/rose/af_rose.c;
or (6) a raw CAN socket, related to the raw_getname function in
net/can/raw.c.
