Currently there is no bound check for number of logical blocks per page (bmp->db_l2nbperpage). Added the required bound check for the calculation of dmap.This should already be fixed by 11509910c599 ("jfs: jfs_dmap: Validate db_l2nbperpage while mounting") Can you please verify if this problem still exists in v6.5?
