Summary
libsndfile security update
Details

Libsndfile is a C library for reading and writing files containing sampled sound such as MS Windows WAV and the Apple/SGI AIFF format through one standard library interface.

Security Fix(es):

libsndfile 1.2.2 contains a misaligned memory access issue in psf_binheader_readf() while parsing WAV fmt chunks. A specially crafted WAV file can cause the function to cast an unaligned destination address to unsigned int * and perform a 4-byte store. This results in undefined behavior leading to denial of service.(CVE-2026-88386)
