Exploitation evidence

Disclosed: evidence found.
CVE published 9 Feb 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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 2026-10-26.

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.

AI-suggested

Red Hat has released security updates that fix these vulnerabilities in FontForge for Red Hat Enterprise Linux 9.6 Extended Update Support. Users should apply these official patches promptly. For update instructions, refer to https://access.redhat.com/articles/11258. No additional mitigations are indicated by the vendor advisory.

Description

FontForge is a font editor for outline and bitmap fonts. It supports a range of font formats, including PostScript (ASCII and binary Type 1, some Type 3 and Type 0), TrueType, OpenType (Type2) and CID-keyed fonts. Security Fix(es): * fontforge: FontForge: Remote Code Execution via heap-based buffer overflow in BMP file parsing (CVE-2025-15279) * fontforge: FontForge: Remote Code Execution via Use-After-Free in SFD file parsing (CVE-2025-15269) * fontforge: FontForge: Arbitrary code execution via SFD file parsing buffer overflow (CVE-2025-15275) 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

Successful exploitation of these vulnerabilities could allow an attacker to execute arbitrary code remotely on affected systems running vulnerable versions of FontForge. This poses a significant security risk, potentially leading to full system compromise.

Summary

FontForge contains multiple critical vulnerabilities that allow remote code execution due to memory corruption issues: a heap-based buffer overflow in BMP file parsing (CVE-2025-15279), a use-after-free vulnerability in SFD file parsing (CVE-2025-15269), and a buffer overflow in SFD file parsing (CVE-2025-15275). These vulnerabilities affect Red Hat CodeReady Linux Builder for Extended Update Support 9.6 across multiple architectures. Red Hat has released security updates to fix these issues as detailed in advisory RHSA-2026:2213.

CWE-416Use After Free (opens in a new tab)
Variant weaknessLikelihood of exploit: HighCWE Top 25 (2025): #7
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
Architecture and Design · Language Selection
Choose a language that provides automatic memory management.
Implementation · Attack Surface Reduction
When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.

CWE-122Heap-based Buffer Overflow (opens in a new tab)
Variant weaknessLikelihood of exploit: HighCWE Top 25 (2025): #16
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
Pre-design: Use a language or compiler that performs automatic bounds checking.
Architecture and Design
Use an abstraction library to abstract away risky APIs. Not a complete solution.
Operation · Build and Compilation · Environment Hardening
Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index…
