Exploitation evidence

Disclosed: evidence found.

Detectable: no evidence on record.
No public nuclei template indexed

No public exploit code indexed in Metasploit or Exploit-DB

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade SUSE to 9.6.

AI-suggested

Red Hat has released updated glib2 packages for Red Hat Enterprise Linux 9 and related variants to fix these vulnerabilities. Users should apply the available security updates as detailed in the Red Hat advisory RHSA-2025:11140. For update instructions, refer to https://access.redhat.com/articles/11258. No additional mitigation steps are specified or required beyond applying the official patches.

Description

GLib provides the core application building blocks for libraries and applications written in C. It provides the core object system used in GNOME, the main loop implementation, and a large set of utility functions for strings and common data structures. Security Fix(es): * glib: buffer overflow in set_connect_msg() (CVE-2024-52533) * glib: Buffer Underflow on GLib through glib/gstring.c via function g_string_insert_unichar (CVE-2025-4373) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Impact

The vulnerabilities involve memory corruption issues (buffer overflow and underflow) in GLib, which could affect applications relying on this library. The advisory rates the impact as moderate. There are no known exploits in the wild at this time. The vulnerabilities could potentially lead to application crashes or other unintended behavior if exploited.

Summary

This advisory covers two security vulnerabilities in the GLib library used in Red Hat Enterprise Linux 9 and related distributions. CVE-2024-52533 is a buffer overflow vulnerability in the set_connect_msg() function, and CVE-2025-4373 is a buffer underflow vulnerability in the g_string_insert_unichar function within glib/gstring.c. Both vulnerabilities stem from improper memory handling in GLib's core utility functions. The issues could potentially lead to memory corruption. Red Hat has released updated glib2 packages to address these vulnerabilities.

CWE-193Off-by-one Error (opens in a new tab)
Base weakness
A product calculates or uses an incorrect maximum or minimum value that is 1 more, or 1 less, than the correct value.
Implementation
When copying character arrays or using character manipulation methods, the correct size parameter must be used to account for the null terminator that needs to be added at the end of the array.
From MITRE CWE, MITRE CAPEC and OWASP (Top 10, OpenCRE).
CWE-124Buffer Underwrite ('Buffer Underflow') (opens in a new tab)
Base weaknessLikelihood of exploit: Medium
The product writes to a buffer using an index or pointer that references a memory location prior to the beginning of the buffer.
Requirements
Choose a language that is not susceptible to these issues.
Implementation
All calculated values that are used as index or for pointer arithmetic should be validated to ensure that they are within an expected range.
