Description Marcel Holtmann 2007-03-13 18:24:56 UTC
A user can supply len < 0 in ipv6_getsockopt_sticky and cause a leak of kernel
memory.

Hi Marcel -

This patch doesn't appear to be needed - len is ignored when copying header info
to the user's buffer in ipv6_getsockopt_sticky() -- the length to hand back to
userspace is taken direclty from the header.  

I don't see this patch upstream.  Let me know if I've missed the vulnerablity
here.
