They're in current process's vm. You just have to parse it yourself.
something along the (untested) lines:
struct mm_struct *mm = current ? get_task_mm(current) : NULL;
if (mm) {
unsigned env_len = mm->env_end - mm->env_start;
char* env = kmalloc(env_len, GFP_KERNEL);
access_process_vm(current, mm->env_start, env,
env_len, 0);
/* env is now a big buffer containing null-terminated
strings representing evironment variables */
mmput(mm);
}
