CVE-2025-32913: Libsoup: null pointer dereference in soup_message_headers_get_content_disposition when "filename" parameter is present, but has no value in content-disposition header

A flaw was found in libsoup, where the soup_message_headers_get_content_disposition() function is vulnerable to a NULL pointer dereference. This flaw allows a malicious HTTP peer to crash a libsoup client or server that uses this function.

Security readout for executives and security teams

Plain-English summary

CVE-2025-32913 is a denial-of-service flaw in libsoup. A malicious HTTP peer can send a malformed Content-Disposition header that crashes software using an affected libsoup function. The impact is service interruption, not data theft or code execution based on the supplied sources.

Executive priority

Treat this as high priority for availability-sensitive systems using libsoup. It is not described as code execution, but remote unauthenticated crashes can still disrupt customer-facing services and operational tooling.

Technical view

libsoup’s soup_message_headers_get_content_disposition() can dereference NULL when a Content-Disposition header includes a filename parameter with no value. The CVSS 3.1 score is 7.5: network reachable, low complexity, no privileges or user interaction, with high availability impact only.

Likely exposure

Exposure is most likely where Linux clients or servers use affected libsoup packages, especially listed Red Hat Enterprise Linux 7 ELS, 8, 8.x extended streams, and 9 variants. RHEL 10 libsoup3 is marked unaffected in the bundle.

Exploitation context

The bundle does not show CISA KEV listing or cited active exploitation. It supports a remotely triggerable crash by a malicious HTTP peer when vulnerable software calls the affected header-parsing function. No exploit maturity or public weaponization evidence is provided.

Researcher notes

Evidence points to CWE-476 NULL pointer dereference in Content-Disposition parsing. Validation should focus on dependency reachability: installed vulnerable package plus application code paths that call soup_message_headers_get_content_disposition() on untrusted HTTP headers.

Mitigation direction

  • Apply relevant vendor security updates for affected libsoup packages.
  • Prioritize internet-facing services and clients that process untrusted HTTP responses or requests.
  • Check Red Hat and distribution advisories for exact fixed package versions.
  • Reduce exposure of services using libsoup until updates are deployed.
  • Monitor for repeated crashes tied to malformed HTTP Content-Disposition headers.

Validation and detection

  • Inventory systems with installed libsoup or distribution packages referencing this CVE.
  • Map package versions against the affected Red Hat product/version list.
  • Confirm RHEL 10 libsoup3 systems are not treated as affected without other evidence.
  • Review application crash logs for libsoup-related header parsing failures.
  • Verify vendor advisory status after patching through package manager metadata.
