Which versions of os_socketaddr are affected by GHSA-C439-CHV8-8G2J?

os_socketaddr (rust) versions < 0.2.2 is affected.

Is there a fix for GHSA-C439-CHV8-8G2J?

Yes. GHSA-C439-CHV8-8G2J is fixed in 0.2.2. Upgrade to this version or later.

Is GHSA-C439-CHV8-8G2J exploitable, and should I be worried?

Whether GHSA-C439-CHV8-8G2J is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

What actually determines whether GHSA-C439-CHV8-8G2J is exploitable, and how bad it is?

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.

Summary

os_socketaddr invalidly assumes the memory layout of std::net::SocketAddr

The os_socketaddr crate has assumed std::net::SocketAddrV4 and std::net::SocketAddrV6 have the same memory layout as the system C representation sockaddr. It has simply casted the pointers to convert the socket addresses to the system representation.

These layout were changed into idiomatic rust types in nightly std. Starting from rustc 1.64 the affected versions of this crate will have undefined behaviour.

Impact

Affected versions

os_socketaddr (< 0.2.2)

Security releases

os_socketaddr → 0.2.2 (rust)

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
