CVE-2026-25638
Description
A flaw was found in ImageMagick, a free and open-source software used for editing and manipulating digital images. A remote attacker could exploit this vulnerability by providing a specially crafted image file. This flaw occurs because the WriteMSLImage function in coders/msl.c returns early without releasing allocated resources, leading to a memory leak. This can result in a Denial of Service (DoS) condition, making the system or application unavailable.
Statement
A MODERATE impact memory leak exists in ImageMagick's MSL encoder, where unreleased resources can lead to denial of service due to resource exhaustion. This affects Red Hat Enterprise Linux 6 ELS and 7 ELS, where ImageMagick is used for image processing.
Mitigation
To mitigate this issue, avoid processing untrusted MSL (Magick Scripting Language) files with ImageMagick. If ImageMagick is deployed in a server environment, consider implementing resource limits for processes handling image conversions to prevent complete resource exhaustion.
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).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (Other); DoS: Resource Consumption (Memory); DoS: Resource Consumption (CPU)
An attacker that can influence the allocation of resources that are not properly released could deplete the available resource pool and prevent all other processes from accessing the same type of resource. Frequently-affected resources include memory, CPU, disk space, power or battery, etc.
