CVE-2026-109278— ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 Memory Leak in Wavelet-Denoise Operation

Quick assessment

Affected
ImageMagick ImageMagick
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 ImageMagick 版本低于 6.9.13-57 和 7.x 版本低于 7.1.2-32 的软件中，wavelet-denoise（小波降噪）操作存在内存泄漏问题。当无法获取所需资源时，该操作未能释放已分配的内存。攻击者可以在资源受限的环境中反复触发 wavelet-denoise 处理过程，从而导致内存泄漏，并降低服务的可用性。

Vulnerability Title
ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 Memory Leak in Wavelet-Denoise Operation
Source: CVE Program / CVE List V5
Vulnerability Description
ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains a memory leak in the wavelet-denoise operation, which fails to release allocated memory when a required resource cannot be acquired. Attackers can repeatedly trigger wavelet-denoise processing under resource-constrained conditions to leak memory and degrade service availability.
