CVE-2026-58011
MEDIUM 6.5 PoC AVAILABLEA 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.
Public exploit or PoC code exists. Modeled probability is still low, but the barrier to attack is reduced — watch closely.
