CVE-2026-129264Sox NG sox_ng out-of-bounds write
CVE-2026-129264 is a out-of-bounds write in Sox NG sox_ng, rated low (2.0 on CVSS 4.0).
Why this priority: Low severity, with no exploitation signal.
Published · Updated · NVD status: Deferred
What it is
Code writes past the end of a buffer, corrupting memory in ways an attacker can often turn into code execution. Code reads or writes outside the memory it was given, which can corrupt the process.
How it is reached
An attacker can exploit it over the network, with an ordinary user account, but someone has to act first, such as opening a file or following a link.
What an attacker gains
The direct impact is limited: partial access to data or a partial outage. In practice, this kind of flaw lets an attacker crash the process, read memory, or in the worst case run code.
Is it being exploited?
There is no public report of exploitation yet.
What to do
- No fixed version is listed yet. Find every place Sox NG sox_ng runs, watch the references for a fix, and plan a replacement if it is no longer supported.
- While there is no fix, review who holds accounts that can reach it.
- Warn the people who use it, and filter files and links on the way in.
Description from NVD
A security vulnerability has been detected in sox_ng up to 14.8.1. Affected by this issue is the function read_samples_voc of the file src/voc.c of the component VOC Decoder. Such manipulation leads to out-of-bounds write. The attack can be executed remotely. The exploit has been disclosed publicly and may be used. The name of the patch is 0b40408b. A patch should be applied to remediate this issue. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- Native code: operating systems, browsers and firmware. The flaw sits wherever native code reads untrusted data.
- Network appliances and media or file parsers. The flaw sits wherever native code reads untrusted data.
Trust boundaries in play
- Authenticated network access. An account is needed, so exposure follows who can sign in: customers, partners or staff.
- People who open files and links. Mail, chat and browsers are the delivery path.
- Wherever native code reads untrusted data. An attacker who crosses it can crash the process, read memory, or in the worst case run code.
Questions to answer about your own systems
- Where does Sox NG sox_ng run in your systems, and at which version?
- Which of those instances can be reached from the internet or partner networks?
- What can it reach once compromised: which data stores, secrets and services?
