FKIE_CVE-2025-34297

Vulnerability from fkie_nvd - Published: 2025-12-01 19:15 - Updated: 2026-10-18 20:10
Severity
8.6 (High) - CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
Summary
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.

El par\u00e1metro nfft no se valida antes de ser utilizado en un c\u00e1lculo de tama\u00f1o (sizeof(kiss_fft_cpx) * (nfft - 1)), lo que puede envolver a un valor peque\u00f1o cuando nfft es grande.
