How to fix?

Upgrade SLES:15.1 nodejs10 to version 10.23.1-1.30.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs10 package and not the nodejs10 package as distributed by SLES. See How to fix? for SLES:15.1 relevant fixed versions and status.

Node.js versions before 10.23.1, 12.20.1, 14.15.4, 15.5.1 are vulnerable to a use-after-free bug in its TLS implementation. When writing to a TLS enabled socket, node::StreamBase::Write calls node::TLSWrap::DoWrite with a freshly allocated WriteWrap object as first argument. If the DoWrite method does not return an error, this object is passed back to the caller as part of a StreamWriteResult structure. This may be exploited to corrupt memory leading to a Denial of Service or potentially other exploits.
