Let H be the Hermite operator
$-\Delta +|x|^2$ on 
$\mathbb {R}^n$. We prove a weighted 
$L^2$ estimate of the maximal commutator operator 
$\sup _{R>0}|[b, S_R^\lambda (H)](f)|$, where 
$ [b, S_R^\lambda (H)](f) = bS_R^\lambda (H) f - S_R^\lambda (H)(bf) $ is the commutator of a BMO function b and the Bochner–Riesz means 
$S_R^\lambda (H)$ for the Hermite operator H. As an application, we obtain the almost everywhere convergence of 
$[b, S_R^\lambda (H)](f)$ for large 
$\lambda $ and 
$f\in L^p(\mathbb {R}^n)$.
