This issue was patched in RHSA-2026:8838.

NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby4.0 package and not the ruby4.0 package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

The dl module in Ruby 1.8.5 and earlier, 1.8.6 through 1.8.6-p286, 1.8.7 through 1.8.7-p71, and 1.9 through r18423 does not check "taintness" of inputs, which allows context-dependent attackers to bypass safe levels and execute dangerous functions by accessing a library using DL.dlopen.
