The main suspects would be NAT and TCPMSS. Did you also try whether

I've just compiled out CONFIG_BRIDGE_NETFILTER and can no longer access
the address the way I was doing it, so that's a no-go for me.
That's really weird since you're apparently not using any bridge
netfilter features. It shouldn't have any effect besides changing
at which point ip_tables is invoked. How are your network devices
configured (specifically any bridges)?
Something in the kernel does
u16 *ptr = addr (given by kmalloc())
ptr[-1] = 0;
Could be an off-one error in a memmove()/memcopy() or loop...
I cant see a network issue here.
So far me neither, but netfilter appears to trigger the bug.
Would it help if I tried some older kernels? This issue only surfaced
for me recently as I only installed the VM's in question about 12 weeks
ago and have only just started really using them in anger. I could try
reproducing it on progressively older kernels to see if I can find one
that works and then bisect from there.
