The nfft parameter is not validated before being used in a size calculation (sizeof(kiss_fft_cpx) * (nfft &#8211; 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>\n<p>Severity: 8.6 | HIGH<\/p>\n<p>Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID : CVE-2025-34297 Published : Dec. 1, 2025, 7:15 p.m. | 1\u00a0hour, 9\u00a0minutes ago Description : 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.
