The (low speed) stall is loss of lift due to high angle of attack.
Agreed, but it is too simplistic to separate mach buffet and angle of attack, because the shock waves vary with angle of attack.
The following picture is from NACA Technical Note 1390 "Effect of compressibility on the distribution of pressures over a tapered wing of NACA 230-series airfoil section" (1947).
