KissFFT could be made to crash or run programs if it received specially crafted input. Software Description: - kissfft: Mixed-radix Fast Fourier Transform library Details: It was discovered that KissFFT incorrectly handled certain large Fourier transform sizes on 32-bit architectures. An attacker could possibly use this issue to cause KissFFT to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2025-34297) It was discovered that KissFFT incorrectly handled certain multidimensional Fourier transform sizes. An attacker could possibly use this issue to cause KissFFT to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2026-41445)
