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.</p> <p><strong>Affected:</strong> Ubuntu:Pro:22.04:LTS: kissfft, Ubuntu:Pro:24.04:LTS: kissfft, Ubuntu:25.10: kissfft, Ubuntu:Pro:26.04:LTS: kissfft</p> <p>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.
