Actually, to correct OP, this has nothing to do with X86_32, it affects only newish X32 abi.
That is right. But a 'CONFIG_X86_X32' flag is not available in openSUSE 12.3 kernel configuration.
On an openSUSE 12.3 system I started:
zcat /proc/config.gz |grep 'CONFIG_X86_X32'
There was empty output. That means even a "# CONFIG_X86_X32" was not available.
It definitely was, even openSUSE 12.2 already had it. Are you sure you checked on a x86-64 host? CONFIG_X86_X32 is an X86_64-only setting.
Hi all, This is shelved subject already but nevertheless, just wanted to link to a very good writeup explaining the ABI in question, its bug and the actual exploit, for anyone interested: http://blog.includesecurity.com/2014/03/exploit-CVE-2014-0038-x32-recvmmsg-k...
