Upgrade RHEL:10 curl to version 0:8.23.0-0.1.hum1 or higher.
This issue was patched in RHSA-2026:82895.

NVD Description

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

When CURLOPT_INTERFACE (or the command line tool's --interface option) is set with one of the documented prefixes (if!, host!, ifhost!), that binding is not part of the connection reuse key, so a later transfer asking for a different source can silently reuse an existing connection and go out from the earlier transfer's source address
