CVE-2026-3394
Published: 01 March 2026
Summary
CVE-2026-3394 is a medium-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Solhsa Soloud. Its CVSS base score is 4.8 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 9.4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Deeper analysis
CVE-2026-3394 is a memory corruption vulnerability (CWE-119) in the SoLoud audio library, specifically versions up to 20200207 maintained by jarikomppa. The issue resides in the SoLoud::Wav::loadwav function within the file src/audiosource/wav/soloud_wav.cpp, part of the WAV File Parser component. Manipulation of a WAV file triggers the corruption, as documented in the CVE published on 2026-03-01 with a CVSS v3.1 base score of 3.3 (AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L).
The vulnerability requires local access and low privileges to exploit, with low attack complexity and no user interaction needed. An attacker can provide a malicious WAV file to the affected SoLoud instance, resulting in memory corruption that leads to a limited denial-of-service impact on availability, without compromising confidentiality or integrity.
References indicate the project was notified early via GitHub issue #401 but has not responded, with no patches or mitigations released. A public proof-of-concept exploit is available at https://github.com/oneafter/0209/blob/main/so2/repro. Additional details appear in VulDB entries (ctiid.348280 and id.348280) and the SoLoud repository at https://github.com/jarikomppa/soloud/.
Security practitioners should audit applications using SoLoud up to 20200207 for WAV file processing and consider isolating or disabling the feature until the maintainer addresses the issue, given the public exploit availability.

Why these techniques?
Memory corruption in WAV parser directly enables local application exploitation resulting in DoS (availability impact only).

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation of untrusted WAV input before it reaches the vulnerable SoLoud::Wav::loadwav parser, blocking the memory corruption trigger.
Enforces memory protection mechanisms that can contain or block the corruption occurring inside the WAV File Parser component.
Allows disabling WAV file processing or the entire SoLoud library until the unpatched vulnerability is addressed, limiting exposure to the public exploit.
