Abstract
Regular black holes are generically unstable because of the classical phenomenon that goes by the name of "mass inflation"which destabilizes the inner horizon. In a recent article, [A. Bonanno, A.-P. Khosravi, and F. Saueressig, Phys. Rev. D 107, 024005 (2023)PRVDAQ2470-001010.1103/PhysRevD.107.024005], it is argued that semiclassical effects due to Hawking radiation can cure this instability, and some concerns are raised against the validity of previous analyses showing its existence in the first place. In this short comment, we explain our reservations regarding these recent claims, and reiterate the relevance of the mass inflation instability for regular black holes of astrophysical interest.
