{"identifier":"CVE-2026-77014","cve":{"id":"CVE-2026-77014","description":"A flaw was found in libsoup's SoupServer HTTP Range header processing. The sort_ranges() comparator in soup-message-headers.c truncates a 64-bit subtraction result to 32-bit int, flipping the sign for range offsets differing by more than INT_MAX. This causes silent omission of requested byte ranges from HTTP 206 Partial Content responses on resources larger than approximately 2 GB.","published":"2026-08-20T09:16:48.167000+00:00","modified":"2026-10-27T10:10:00.240000+00:00","status":"Awaiting Analysis","score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","cvss_version":"3.1","affected":[],"weaknesses":["CWE-197"],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-77014","source":"secalert@redhat.com"},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2520143","source":"secalert@redhat.com"},{"url":"https://gitlab.gnome.org/GNOME/libsoup/-/merge_requests/550","source":"secalert@redhat.com"}],"kev":null,"kev_checked":true,"metrics":{"cvssMetricV31":[{"source":"secalert@redhat.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","baseScore":5.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":1.4}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-08-25T14:23:45.467216Z","id":"CVE-2026-77014","options":[{"exploitation":"none"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"configurations":[],"source":"nvd","retrieved_at":"2026-10-28T10:25:56.889236+00:00","exploited":false,"kev_stale":false,"products":[],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence."]},"epss":{"probability":0.00232,"percentile":0.14043,"date":"2026-10-27","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"access.redhat.com","source_url":"https://access.redhat.com/security/cve/CVE-2026-77014","investigate_url":"https://investigate.aeglixmind.com/#access.redhat.com"},{"domain":"bugzilla.redhat.com","source_url":"https://bugzilla.redhat.com/show_bug.cgi?id=2520143","investigate_url":"https://investigate.aeglixmind.com/#bugzilla.redhat.com"},{"domain":"gitlab.gnome.org","source_url":"https://gitlab.gnome.org/GNOME/libsoup/-/merge_requests/550","investigate_url":"https://investigate.aeglixmind.com/#gitlab.gnome.org"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-77014","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-77014","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-77014","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
