CVE-2026-25988
Description
A flaw was found in ImageMagick. When processing certain images, the msl.c component fails to correctly update the stack index, causing an image to be stored in an incorrect memory location. This memory is then not properly freed, leading to memory leaks. A remote attacker could exploit this vulnerability by providing a specially crafted image, which can lead to a Denial of Service (DoS) condition.
Statement
MODERATE: A flaw in ImageMagick can lead to memory leaks when processing images. This issue arises because the MSL image stack index is not consistently refreshed, causing images to be stored in incorrect memory locations and not properly deallocated. Red Hat products utilizing ImageMagick for image manipulation may experience resource exhaustion under specific processing conditions.
Mitigation
To reduce the risk of memory exhaustion, it is recommended to avoid processing untrusted or maliciously crafted image files with ImageMagick. Deploying ImageMagick operations within a sandboxed environment with appropriate resource limits can further contain potential impacts from this vulnerability.
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 (Memory); DoS: Resource Consumption (Other)
An adversary that can cause a resource counter to become inaccurate may be able to create situations where resources are not accounted for and not released, thus causing resources to become scarce for future needs.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
An adversary that can cause a resource counter to become inaccurate may be able to force an error that causes the product to crash or exit out of its current operation.
