What is GHSA-29C2-65RJ-H343?

GHSA-29C2-65RJ-H343 is a medium-severity security vulnerability in ckb (rust), affecting versions >= 0.39.0-rc1, < 0.39.0. It is fixed in 0.39.0, 0.35.2, 0.36.1, 0.37.1, 0.38.2.

Which versions of ckb are affected by GHSA-29C2-65RJ-H343?

ckb (rust) versions >= 0.39.0-rc1, < 0.39.0 is affected.

Is there a fix for GHSA-29C2-65RJ-H343?

Yes. GHSA-29C2-65RJ-H343 is fixed in 0.39.0, 0.35.2, 0.36.1, 0.37.1, 0.38.2. Upgrade to this version or later.

Is GHSA-29C2-65RJ-H343 exploitable, and should I be worried?

Whether GHSA-29C2-65RJ-H343 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-29C2-65RJ-H343 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.

How do I fix GHSA-29C2-65RJ-H343?

Upgrade: ckb to 0.39.0 or later, ckb to 0.35.2 or later, ckb to 0.36.1 or later, ckb to 0.37.1 or later, ckb to 0.38.2 or later.

Summary

Nervos CKB Permit load cell data from memory

Impact

The faulty nodes will reject transactions which calls load_cell_data syscall but the input cell is still in the mempool. They also ban other nodes and cause the network separation.

Affected versions

ckb (>= 0.39.0-rc1, < 0.39.0) ckb (>= 0.35.0-rc1, < 0.35.2) ckb (>= 0.36.0-rc1, < 0.36.1) ckb (>= 0.37.0-rc1, < 0.37.1) ckb (>= 0.38.0-rc1, < 0.38.2)

Security releases

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.
