CVE-2026-116158
Description
A flaw was found in ImageMagick. A missing cleanup operation during failed compare routines causes an unreleased memory leak. An attacker could supply crafted inputs that trigger repeated comparison errors, resulting in excessive resource consumption and leading to a Denial of Service (DoS).
Statement
This vulnerability is rated with a Low impact because ImageMagick utilities in Red Hat environments are primarily executed as ephemeral CLI tasks where allocated memory is immediately reclaimed by the kernel upon process exit. A denial of service requires an attacker to convince a user or automated service to repeatedly process malformed inputs through a long-running, persistent process that fails to restart or manage memory across failed comparison operations. The issue presents no threat to data confidentiality or system integrity.
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.
