  Cross-talk is a well-known feature of single-photon avalanche detectors. It
is especially important to account for this effect in applications involving
coincidences of two or more photons registered by the sensor since in this case
the cross-talk may mimic the useful signal. In this work, we characterize the
cross-talk of the LinoSPAD2 detector, as well as perform joint measurements of
the cross-talk and Hanbury Brown - Twiss two-photon interference, comparing and
cross-calibrating both effects. With a median dark count rate of 125 cps/pixel,
we report the average cross-talk probability of $0.22~\%$ for the nearest
neighbor and also observe a long-range cross-talk of the order $2 \cdot
10^{-5}~\%$ for channels separated by up to 20 pixels.
