This issue was patched in RHSA-2022:6963.

NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs-full-i18n package and not the nodejs-full-i18n package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

A weak randomness in WebCrypto keygen vulnerability exists in Node.js 18 due to a change with EntropySource() in SecretKeyGenTraits::DoKeyGen() in src/crypto/crypto_keygen.cc. There are two problems with this: 1) It does not check the return value, it assumes EntropySource() always succeeds, but it can (and sometimes will) fail. 2) The random data returned byEntropySource() may not be cryptographically strong and therefore not suitable as keying material.
