Both messages sohu0106 posted initially had the Subject of "CVE request:
kernel stack infoleaks", which I changed to the two more specific
Subjects before approving the messages.  (I do that to especially
non-descriptive Subjects from time to time, as long as the messages were
not CC'ed to elsewhere.  I leave message bodies entirely intact.)

Thus, sohu0106 wanted to request the CVEs from this list, and apparently
didn't request them elsewhere.  sohu0106, this list is no longer a place
to request CVEs from, but we appreciate the vulnerability notifications.
You may request the CVEs from and then post
them in here, "replying" to your own messages on the list.

sohu0106, have you also reported these issues upstream?  For the
net/irda/af_irda.c issue, from the MAINTAINERS file:

M:      Samuel Ortiz <>
L: (subscribers-only)
S:      Maintained
T:      git git://
F:      Documentation/networking/irda.txt
F:      drivers/net/irda/
F:      include/net/irda/
F:      net/irda/

For the driver/video/fbdev/aty/atyfb_base.c issue I guess it's, although there's no perfect match for that
filename.  In both cases, CC the messages to LKML.
