CVE-2026-58011 Glib: out-of-bounds read in glib/gdatetime.c:g_date_time_get_ymd via invalid gdatetime

Description

A flaw was found in GLib. An out-of-bounds read of only 2 bytes can occur in the g_date_time_get_ymd function in the glib/gdatetime.c file when an invalid GDateTime object produced by the g_date_time_add_full function is processed. This flaw can corrupt the date output and potentially cause logic errors that may lead to a denial of service.
