Last modified Jun 17, 2026

CVE-2025-6052 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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. EPSS estimates a 0.42% chance of exploitation in the next 30 days.

Description

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.
