Let $M$ be an $n$-dimensional closed oriented smooth manifold with $n\equiv 4\;\text{mod}\;8$, and $\unicode[STIX]{x1D702}$ be a complex vector bundle over $M$. We determine the final obstruction for $\unicode[STIX]{x1D702}$ to admit a stable real form in terms of the characteristic classes of $M$ and $\unicode[STIX]{x1D702}$. As an application, we obtain the criteria to determine which complex vector bundles over a simply connected four-dimensional manifold admit a stable real form.
