  Aug 17  RESCORED — CVE-2026-58011 (GNOME GLib). CVSS 6.5 → 7.5 (NVD).

CWE-125 · CNA: redhat · CVSS v3.1 · 53 references · NVD status: Modified

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.
