There are 2 electrons in the antibonding orbitals of \mathrm{CO}.
The electronic configuration of CO (14 electrons) can be given as:
\mathrm{\begin{aligned} & \sigma 1 \mathrm{~s}^2 \\ & \sigma^* 1 \mathrm{~s}^2 \\ & \sigma 2 \mathrm{~s}^2 \\ & \sigma^* 2 \mathrm{~s}^2 \\ & \pi 2 \mathrm{p}_{\mathrm{x}}^2=\pi 2 \mathrm{p}_{\mathrm{y}}^2 \\ & \sigma_2 \mathrm{p}_{\mathrm{z}} \end{aligned} }

(Where, \sigma and \pi represents the bonding molecular orbitals and \sigma^*, \pi^* represents the antibonding molecular orbitals )
