CVE-2026-109276
Description
A flaw was found in ImageMagick. A remote attacker can cause a Denial of Service (DoS) by submitting crafted JPEG Network Graphics (JNG) images for processing. The JNG decoder fails to remove temporary files during the handling of these inputs, leading to excessive disk space consumption.
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.

Technical Impact: Other; Read Application Data; Modify Application Data; DoS: Resource Consumption (Other)
It is possible to overflow the number of temporary files because directories typically have limits on the number of files allowed. This could create a denial of service problem.
