CVE-2025-6052

7.5 highEPSS 0.5%

High (7.5) in gnome glib. EPSS 0.5% chance of exploitation in the next 30 days.

A flaw was found in how GLib’s GString manages memory when adding data to strings. If a string is already very large, combining it with more input can cause a hidden overflow in the size calculation. This makes the system think it has enough memory when it doesn’t. As a result, data may be written past the end of the allocated memory, leading to crashes or memory corruption.
