Hi, The following vulnerability was published for kissfft. CVE-2025-34297[0]: | 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. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
