The stability of the $n=m=1$ alpha-fishbone kinetic-MHD mode on the ITER 15MA baseline scenario \cite{ITERB} is analyzed using the nonlinear hybridKinetic-MHD code XTOR-K. Quantitative agreement is found between the complexfrequencies $\omega + i\gamma$ computed with the linear model in\cite{Brochard2018} and XTOR-K's linear simulations. Identical precessionalresonance positions in phase space are also found between the linear model andXTOR-K. Linear hybrid simulations performed with XTOR-K on the ITER 15 MAscenario reveal that this configuration is likely to be unstable against thealpha fishbone mode. The fishbone thresholds for kinetic-MHD equilibria withflat q profiles with on-axis safety factor just below unity lies between$\beta_{\alpha,thres}/\beta_{tot} = 6-10\%$, whereas the expected beta ratio onITER is $\beta_{\alpha}/\beta_{tot} = 15-20\%$ \cite{ITERB}.
