KissFFT versions prior to the fix commit 1b083165 contain an integer overflow in kiss_fft_alloc() in kiss_fft.c on platforms where size_t is 32-bit. The nfft parameter is not validated before being used in a size calculation (sizeof(kiss_fft_cpx) * (nfft - 1)), which can wrap to a small value when nfft is large. As a result, malloc() allocates an undersized buffer and the subsequent twiddle-factor initialization loop writes nfft elements, causing a heap buffer overflow. This vulnerability only affects 32-bit architectures.

The remote Ubuntu 22.04 LTS / 24.04 LTS / 26.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8745-1 advisory.

    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)

    Two issues have been found in kissfft, a mixed-radix Fast Fourier     Transform library. The issues are related to integer overflows.



    For Debian 11 bullseye, these problems have been fixed in version     131.1.0-1+deb11u1.

    We recommend that you upgrade your kissfft packages.
