Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Ongoing control assessments and code testing (static/dynamic analysis, fuzzing) surface memory buffer restriction failures, which are then remediated before release.
Managed runtimes used by platform-independent applications (e.g., JVM, CLR) enforce memory safety, preventing most buffer overflows that require direct memory manipulation.
Memory protections (e.g., W^X, ASLR) make exploitation of buffer-boundary violations far harder to turn into code execution.
Detects exploitation attempts that produce memory corruption, crashes, or anomalous behavior.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Memory corruption in WAV parser directly enables local application exploitation resulting in DoS (availability impact only).
NVD Description
A vulnerability was detected in jarikomppa soloud up to 20200207. This affects the function SoLoud::Wav::loadwav of the file src/audiosource/wav/soloud_wav.cpp of the component WAV File Parser. Performing a manipulation results in memory corruption. The attack must be initiated from a local…

position. The exploit is now public and may be used. The project was informed of the problem early through an issue report but has not responded yet.
Deeper analysisAI
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.
