CVE-2026-22770
Description
A flaw was found in ImageMagick. The BilateralBlurImage method improperly initializes a memory buffer. This can lead to the release of an invalid pointer if memory allocation fails. A remote attacker could exploit this vulnerability to cause a Denial of Service (DoS) by providing a specially crafted image, leading to application instability or crashes.
Statement
This vulnerability is rated Moderate for Red Hat products as it affects ImageMagick, a widely used image processing library. A flaw in the BilateralBlurImage method can lead to a release of an invalid pointer when memory allocation fails, potentially resulting in a denial of service. This issue impacts Red Hat Enterprise Linux 6 ELS, 7 ELS, and Community Projects like EPEL and Fedora.
Mitigation
To mitigate this issue, avoid processing untrusted image files with ImageMagick. If ImageMagick is used in an automated or server-side context, consider implementing sandboxing mechanisms to limit the impact of potential exploitation. Restricting the sources of images processed by ImageMagick to trusted origins can also reduce exposure.
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)
Integrity,Availability,Confidentiality
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; Execute Unauthorized Code or Commands
This weakness may result in the corruption of memory, and perhaps instructions, possibly leading to a crash. If the corrupted memory can be effectively controlled, it may be possible to execute arbitrary code.
