{"cve":"CVE-2025-4948","nvd":{"published":"2025-05-19T16:15:36.790","modified":"2026-11-01T01:17:14.670","status":"Deferred","description":"A flaw was found in the soup_multipart_new_from_message() function of the libsoup HTTP library, which is commonly used by GNOME and other applications to handle web communications. The issue occurs when the library processes specially crafted multipart messages. Due to improper validation, an internal calculation can go wrong, leading to an integer underflow. This can cause the program to access invalid memory and crash. As a result, any application or server using libsoup could be forced to exit unexpectedly, creating a denial-of-service (DoS) risk.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-191"],"references":["https://access.redhat.com/errata/RHSA-2025:21657","https://access.redhat.com/errata/RHSA-2025:8126","https://access.redhat.com/errata/RHSA-2025:8128","https://access.redhat.com/errata/RHSA-2025:8132","https://access.redhat.com/errata/RHSA-2025:8139"],"products":[],"source":"nvd","synced_at":"2026-11-01T01:37:37.021879438+00:00"},"epss":{"cve":"CVE-2025-4948","score":0.00812,"percentile":0.56972,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
