CVE-2026-88386
UnknownSummary
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.
Risk Assessment
An attacker can remotely crash an audio-processing application, causing denial of service. This may disrupt systems that play or process sound.
Recommendation
Upgrade libsndfile to a version newer than 1.2.2 that includes the fix. Until then, avoid processing untrusted WAV files.

An out of bounds read in the function d2ulaw_array() in libsndfile version 1.0.28 may lead to a remote DoS attack or information disclosure, related to mishandling of the NAN and INFINITY floating-point values.
- CVE-2017-14245High
An out of bounds read in the function d2alaw_array() in libsndfile version 1.0.28 may lead to a remote DoS attack or information disclosure, related to mishandling of the NAN and INFINITY floating-point values.
- CVE-2017-6892High
In version 1.0.28 of the libsndfile library, there is an error in the 'aiff_read_chanmap()' function that can be exploited to cause an out-of-bounds read memory access via a specially crafted AIFF file.
- CVE-2017-8361High
The flac_buffer_copy function in flac.c in libsndfile version 1.0.28 allows remote attackers to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted audio file.
- CVE-2015-7805High
A heap-based buffer overflow in libsndfile version 1.0.25 allows remote attackers to exploit the headindex value in the header of an AIFF file.
- CVE-2017-12562Critical
Heap-based buffer overflow in the psf_binheader_writef function in common.c in libsndfile through version 1.0.28 allows remote attackers to cause application crashes or possibly have unspecified other impacts.
- CVE-2026-88372High
libsndfile 1.2.2 contains an integer overflow vulnerability in mat4_read_header() when parsing crafted MAT4 (MATLAB v4) files.
- CVE-2026-37555High
In libsndfile 1.2.2 IMA ADPCM codec, an integer overflow occurs when multiplying samplesperblock and blocks in the WAV code path, leading to incorrect frame count. An attacker can exploit this via a crafted WAV file to cause heap buffer overflow or denial of service.
