Summary
Nervos CKB Pool does not remove the conflicting transactions from the statistics
Workarounds
Restart the CKB node.
Impact
There's a bug in the pool statistics that when conflicting transactions are removed from the pool, they are not subtracted from the statics. Finally, the transaction pool keeps full and reject all transactions.

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.

Frequently Asked Questions
- What is GHSA-H4C3-5275-VRMG? GHSA-H4C3-5275-VRMG is a medium-severity security vulnerability in ckb (rust), affecting versions < 0.39.2. It is fixed in 0.39.2.
- Which versions of ckb are affected by GHSA-H4C3-5275-VRMG? ckb (rust) versions < 0.39.2 is affected.
- Is there a fix for GHSA-H4C3-5275-VRMG? Yes. GHSA-H4C3-5275-VRMG is fixed in 0.39.2. Upgrade to this version or later.
- Is GHSA-H4C3-5275-VRMG exploitable, and should I be worried? Whether GHSA-H4C3-5275-VRMG 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-H4C3-5275-VRMG 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.
