The NVD page for this CVE says it affects Erlang/OTP before 23.2.2 (with ssl application 10.2).

https://nvd.nist.gov/vuln/detail/CVE-2020-35733

The upstream commit that fixes this CVE says that the flaw was introduced in a commit that was first shipped in Erlang/OTP 23.2.

https://github.com/erlang/otp/commit/a59f3c4d2be19343f43c46241d0f4e30dd5563de
https://github.com/erlang/otp/commit/d24a220c3b867caef83026ba31d2656366da4322

EPEL 8 has erlang-22.0.7-1.el8, so it doesn't included the commit that introduced the flaw.  I also confirmed that this version has ssl application 9.3.5.

https://github.com/erlang/otp/blob/OTP-22.0.7/lib/ssl/vsn.mk#L1

Based on all of this, I think NVD's description of "before 23.2.2" actually means "after 23.2, before 23.2.2", not all versions before 23.2.2.  Thus the EPEL 8 package is not affected.
