Abstract: We investigate the stability of the Standard Model vacuum with respect to vacuum tunneling to the Komatsu vacuum, which exists when $m_L^2 + m_{H_u}^2<0$, in the cMSSM. Employing the numerical tools \verb|SARAH|, \verb|SPheno| and \verb|CosmoTransitions|, we scan and constrain the parameter space of the cMSSM up to 10 TeV. Regions excluded due to having a vacuum tunneling half-life less than the age of the observable universe are concentrated near the regions where the Standard Model vacuum is tachyonic and are more stringent at smaller $m_0$, larger and negative $A_0$, and larger $\tan\beta$. New excluded regions, which satisfy $m_h \simeq 125 \text{GeV}$, are found.
