CVE-2026-109278

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.
