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 2026-10-25.

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 Red Hat to 9.8 or 8.8.1.

AI-suggested

Red Hat has released official security updates addressing these vulnerabilities. Users should apply the provided patches for spice-client-win and related packages as detailed in the Red Hat advisories RHSA-2026:0001 and RHSA-2025:11802. Following the vendor's update instructions will mitigate these issues. No additional mitigation steps are indicated by the vendor advisory.

Description

Spice client MSI installers for Windows clients Security Fix(es): * sqlite: Integer Truncation in SQLite (CVE-2025-6965) * libtiff: LibTIFF Use-After-Free Vulnerability (CVE-2025-8176) * libtiff: Libtiff Write-What-Where (CVE-2025-9900) * expat: libexpat in Expat allows attackers to trigger large dynamic memory allocations via a small document that is submitted for parsing (CVE-2025-59375) 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 could allow attackers to cause memory corruption or excessive memory allocation, potentially leading to denial of service or other impacts depending on the context of use. The integer truncation in SQLite may cause incorrect data handling. The libtiff use-after-free and write-what-where vulnerabilities could lead to memory corruption, which may be exploitable. The libexpat issue can cause large memory allocations, potentially leading to denial of service. No active exploitation in the wild has been reported at this time.

Summary

This advisory covers multiple vulnerabilities fixed in spice-client-win MSI installers and related components in Red Hat Enterprise Linux. The integer truncation vulnerability in SQLite (CVE-2025-6965) could lead to incorrect processing of integer values. The libtiff vulnerabilities include a use-after-free (CVE-2025-8176) and a write-what-where condition (CVE-2025-9900), both of which can lead to memory corruption. Additionally, libexpat (CVE-2025-59375) has a flaw allowing attackers to trigger large dynamic memory allocations via crafted XML documents. Red Hat has issued updated packages for affected versions of RHEL 8.8 and 9, covering multiple architectures and update services. The vendor advisory confirms these fixes and provides detailed package information and instructions for applying updates.

CWE-197Numeric Truncation Error (opens in a new tab)
Base weaknessLikelihood of exploit: Low
Truncation errors occur when a primitive is cast to a primitive of a smaller size and data is lost in the conversion.
Implementation
Ensure that no casts, implicit or explicit, take place that move from a larger size primitive or a smaller size primitive.
From MITRE CWE, MITRE CAPEC and OWASP (Top 10, OpenCRE).
CWE-825Expired Pointer Dereference (opens in a new tab)
Base weakness
The product dereferences a pointer that contains a location for memory that was previously valid, but is no longer valid.
Architecture and Design
Choose a language that provides automatic memory management.
Implementation
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.

Base weaknessLikelihood of exploit: High
Any condition where the attacker has the ability to write an arbitrary value to an arbitrary location, often as the result of a buffer overflow.
Architecture and Design · Language Selection
Use a language that provides appropriate memory abstractions.
Operation
Use OS-level preventative functionality integrated after the fact. Not a complete solution.

CWE-770Allocation of Resources Without Limits or Throttling (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #25
The product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated.
Requirements
Clearly specify the minimum and maximum expectations for capabilities, and dictate which behaviors are acceptable when resource allocation reaches limits.
Architecture and Design
Limit the amount of resources that are accessible to unprivileged users. Set per-user limits for resources. Allow the system administrator to define these limits. Be careful to avoid CWE-410.
Architecture and Design
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended.

CWE-120Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #11
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer.
Requirements · Language Selection
Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
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…
