The remote Redhat Enterprise Linux 10 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2025:23437 advisory.

    Libsoup is an HTTP library implementation in C. It was originally part of a SOAP (Simple Object Access     Protocol) implementation called Soup, but the SOAP and non-SOAP parts have now been split into separate     packages.  libsoup uses the Glib main loop and is designed to work well with GTK applications. This     enables GNOME applications to access HTTP servers on the network in a completely asynchronous fashion,     very similar to the Gtk+ programming model (a synchronous operation mode is also supported for those who     want it), but the SOAP parts were removed long ago.

    Security Fix(es):

    * libsoup: Heap Use-After-Free in libsoup message queue handling during HTTP/2 read completion     (CVE-2025-12105)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
