What is GHSA-GW5W-5J7F-JMJJ?

GHSA-GW5W-5J7F-JMJJ is a low-severity security vulnerability in pprof (rust), affecting versions < 0.14.0. It is fixed in 0.14.0.

Which versions of pprof are affected by GHSA-GW5W-5J7F-JMJJ?

pprof (rust) versions < 0.14.0 is affected.

Is there a fix for GHSA-GW5W-5J7F-JMJJ?

Yes. GHSA-GW5W-5J7F-JMJJ is fixed in 0.14.0. Upgrade to this version or later.

Is GHSA-GW5W-5J7F-JMJJ exploitable, and should I be worried?

Whether GHSA-GW5W-5J7F-JMJJ 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-GW5W-5J7F-JMJJ 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

Unsound usages of std::slice::fromrawparts

The library breaks the safety assumptions when using unsafe API std::slice::from_raw_parts. First, when using the API in iterator implementation (TempFdArrayIterator.next), generic type could be any type, which would create and pass a misaligned pointer to the unsafe API. Second, when validating the address, the code passed the type c_void, which could also be any type, leading to potential uninitialized memory exposure.

Two unsound usages here highlight the necessity for developers to perform type checks before doing type conversion with unsafe API.

The panic caused by the misalignment causes several downstream applications (e.g., greptimedb) to crash when using pprof::report::ReportBuilder::build.

This was patched in 0.14.0.

The developer also suggested moving to pprof2.

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.
