Comment 1 Jarek Prokop 2026-04-08 13:51:53 UTC 
After analysis, we determined that this vulnerability is not exploitable for Ruby:

* Reason: This CVE is for OpenSSL and is misreported on Ruby. The bindings carry the same name, but the CVE do not affect Ruby bindings.

Based on this, we are closing this tracker as Not a Bug.
