  This article reports an evaluation on the linear ideal magnetohydrodynamic
(MHD) stability of the China Fusion Engineering Test Reactor (CFETR) baseline
scenario for various first-wall locations. The initial-value code NIMROD and
eigen-value code AEGIS are employed in this analysis. A good agreement is
achieved between two codes in the growth rates of $n=1-10$ ideal MHD modes for
various locations of the perfect conducting first-wall. The higher-$n$ modes
are dominated by ballooning modes and localized in the pedestal region, while
the lower-$n$ modes have more prominent external kink components and broader
mode profiles. The influences of plasma-vacuum profile and wall shape are also
examined using NIMROD. In presence of resistive wall, the low-$n$ ideal MHD
instabilities are further studied using AEGIS. For the designed first-wall
location, the $n = 1$ resistive wall mode (RWM) is found unstable, which could
be fully stabilized by uniform toroidal rotation above 2.9\% core Alfv\'en
speed.
