How to fix?

Upgrade Oracle:8 rubygem-mongo to version 0:2.5.1-2.module+el8.3.0+7756+e45777e9 or higher.
This issue was patched in ELSA-2021-2587.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rubygem-mongo package and not the rubygem-mongo package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

An issue was discovered in Ruby 2.5.x through 2.5.7, 2.6.x through 2.6.5, and 2.7.0. If a victim calls BasicSocket#read_nonblock(requested_size, buffer, exception: false), the method resizes the buffer to fit the requested size, but no data is copied. Thus, the buffer string provides the previous value of the heap. This may expose possibly sensitive data from the interpreter.
