Summary

A flaw was found in libsoup, where the soup_multipart_new_from_message() function is vulnerable to an out-of-bounds read. This flaw allows a malicious HTTP client to induce the libsoup server to read out of bounds.

Although the 7.4 base score maps to an IMPORTANT CVSS severity, Red Hat Product Security has curated the impact of this flaw as MODERATE.

The libsoup, libsoup3, and mingw-libsoup components in Red Hat Enterprise Linux 7, 8, 9, and 10, in Red Hat In-Vehicle OS 1, and in Fedora are listed as affected, and a fix is being pursued through the delegated maintainers for each affected stream; the libsoup component in Red Hat Enterprise Linux 6 Extended Lifecycle Support is out of support scope and no update is planned for that stream.

Weakness: CWE-125.

Affected products named by the advisory: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 7 Extended Lifecycle Support; Red Hat Enterprise Linux 8.2 Advanced Update Support; Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support; and 8 more.

Is CVE-2025-32914 exploited?

No exploitation is reported in the sources VulniPulse tracks: CVE-2025-32914 is not in the CISA KEV catalog (checked ) and this advisory does not report exploitation. That is not proof the vulnerability cannot be exploited.
