CVE-2026-88386: n/a
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.
AI Analysis
Technical Summary
The vulnerability in libsndfile 1.2.2 involves a misaligned memory access in the psf_binheader_readf() function during the parsing of WAV format chunks. Specifically, the function casts an unaligned destination address to an unsigned int pointer and performs a 4-byte store operation. This undefined behavior can cause the application to crash or become unavailable, resulting in a denial of service.
Potential Impact
An attacker can cause a denial of service by providing a specially crafted WAV file that triggers the misaligned memory access in libsndfile 1.2.2. This leads to undefined behavior and application instability or crash.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid processing untrusted WAV files with libsndfile 1.2.2 to mitigate the risk of denial of service.
