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?
Heap buffer overflow in local FLAC parser triggers application crash (A:L, no C/I impact), directly enabling T1499.004 Application or System Exploitation for DoS.
NVD Description
A security vulnerability has been detected in jarikomppa soloud up to 20200207. The impacted element is the function SoLoud::Wav::loadflac of the file src/audiosource/wav/soloud_wav.cpp of the component Audio File Handler. Such manipulation leads to heap-based buffer overflow. The attack must be…

Deeper analysisAI
CVE-2026-3393 is a heap-based buffer overflow vulnerability in the jarikomppa/soloud library, affecting versions up to 20200207. The issue resides in the SoLoud::Wav::loadflac function within the file src/audiosource/wav/soloud_wav.cpp, part of the Audio File Handler component. It is classified under CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-122 (Heap-based Buffer Overflow), 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 with low privileges to exploit, involving low attack complexity and no user interaction. An attacker can trigger the buffer overflow by manipulating FLAC audio files processed through the affected function, potentially causing a denial of service via application crash or limited availability impact, but without confidentiality or integrity effects.
Advisories from VulDB (ctiid.348279 and id.348279) document the issue, noting that the project was informed early via GitHub issue #401 but has not responded. No patches or official mitigations are available yet. A public exploit repro is disclosed at https://github.com/oneafter/0209/blob/main/so1/repro. Security practitioners should avoid using affected soloud versions or validate inputs rigorously when handling FLAC files in audio processing applications.
