CVE-2026-25985
Description
A memory exhaustion vulnerability has been identified in ImageMagick when processing specially crafted SVG image files. In vulnerable versions, a maliciously crafted SVG element may trigger an excessively large internal memory allocation (on the order of hundreds of gigabytes), causing the ImageMagick process to consume all available memory and abort. An application that reads, identifies, or converts such an SVG image may be affected when the file is passed to ImageMagick’s API or command-line tools.
Statement
This issue is classified as High severity by Red Hat Product Security. A remote attacker can craft an SVG image that, when processed by ImageMagick, induces extremely large memory allocation requests, leading to process failure or termination. The attack complexity is low and does not require any privileges or user interaction. While confidentiality and integrity are not directly impacted, the availability of services that parse or manipulate untrusted SVG images could be significantly disrupted over network, justifying a High severity rating.
It is important to note that ImageMagick has been removed from Red Hat Enterprise Linux 8 and later releases. Therefore, current supported RHEL 8 and newer systems are not affected by this issue unless ImageMagick is installed from third-party or custom repositories.
For additional information, refer to https://access.redhat.com/solutions/4437561.
Mitigation
To mitigate this vulnerability, avoid processing untrusted or unverified SVG image files with ImageMagick. When ImageMagick must process SVG files from untrusted sources, consider running the application in a sandboxed environment to limit potential resource exhaustion impacts.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)
When allocating resources without limits, an attacker could prevent other systems, applications, or processes from accessing the same type of resource. It can be easy for an attacker to consume many resources by rapidly making many requests or causing larger resources to be used than is needed.
