The vulnerability occurs while parsing an Authorization or WWW-Authenticate header that uses Digest authentication. Specially crafted whitespace placement around a parameter's terminator can cause an internal length calculation to underflow, leading to a crash of the process parsing the header. On an RTSP server this can be triggered by a remote, unauthenticated attacker sending a single malformed request when the server has authentication enabled; the same flaw can also be triggered against an RTSP client by a malicious or compromised RTSP server. Successful exploitation results in a denial of service (application crash) and has no confirmed impact on confidentiality or integrity."}],"affected":[{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 10","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"gstreamer1-plugins-base","defaultStatus":"affected","versions":[{"version":"0:1.26.7-2.el10_2.2","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/o:redhat:enterprise_linux:10.2"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 8","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"gstreamer1-plugins-base","defaultStatus":"affected","versions":[{"version":"0:1.16.1-7.el8_10","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/a:redhat:enterprise_linux:8::appstream"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 9","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"gstreamer1-plugins-base","defaultStatus":"affected","versions":[{"version":"0:1.22.12-8.el9_8.2","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/a:redhat:enterprise_linux:9::appstream"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 7","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"gstreamer1-plugins-base","defaultStatus":"affected","cpes":["cpe:/o:redhat:rhel_els:7"]}],"references":[{"url":"https://access.redhat.com/errata/RHSA-2026:66460","name":"RHSA-2026:66460","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2026:67145","name":"RHSA-2026:67145","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2026:69100","name":"RHSA-2026:69100","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/security/cve/CVE-2026-85150","tags":["vdb-entry","x_refsource_REDHAT"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2527936","name":"RHBZ#2527936","tags":["issue-tracking","x_refsource_REDHAT"]},{"url":"https://gitlab.freedesktop.org/gstreamer/gstreamer-security/-/merge_requests/120"},{"url":"https://gitlab.freedesktop.org/gstreamer/gstreamer/-/blob/main/subprojects/gst-plugins-base/gst-libs/gst/rtsp/gstrtspmessage.c#L1408"}],"datePublic":"2026-09-03T10:25:00.000Z","problemTypes":[{"descriptions":[{"cweId":"CWE-476","description":"NULL Pointer Dereference","lang":"en","type":"CWE"}]}],"x_redhatCweChain":"CWE-476: NULL Pointer Dereference","workarounds":[{"lang":"en","value":"No mitigation is currently available that meets Red Hat Product Security's standards for usability, deployment, applicability, or stability."}],"timeline":[{"lang":"en","time":"2026-08-26T00:00:00.000Z","value":"Reported to Red Hat."},{"lang":"en","time":"2026-09-03T10:25:00.000Z","value":"Made public."}],"credits":[{"lang":"en","value":"Upstream acknowledges Roy Lau (Independent researcher) as the original reporter."}],"providerMetadata":{"orgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","shortName":"redhat","dateUpdated":"2026-11-06T01:07:55.949Z"},"x_generator":{"engine":"cvelib 1.8.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-03T12:33:40.281754Z","id":"CVE-2026-85150","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-03T12:34:05.679Z"}}]}}
