Thanks for the report, but this isn't a bug. See the final paragraph of https://git-scm.com/docs/user-manual#tree-object. (Said another way, git doesn't track full permisions of files nor ACLs nor creation/modification/access times, or other filesystem-specific data. It's reporting to you the data as recorded in git which for normal files will be either 100644 or 100755.)
