The patch added a size validation check lsize + 8 > size, but it does not account for the GST_ROUND_UP_2(lsize) used in the actual offset calculation. When lsize is an odd number, the parser advances more bytes than validated, causing OOB read.","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-125"],"references":["https://access.redhat.com/security/cve/CVE-2026-1940","https://bugzilla.redhat.com/show_bug.cgi?id=2436932","https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/4854","https://gstreamer.freedesktop.org/security/sa-2026-0001.html","https://security-tracker.debian.org/tracker/CVE-2026-1940"],"products":["debian:debian_linux","freedesktop:gst-plugins-good","gstreamer:gstreamer","redhat:enterprise_linux"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-1940","score":0.00234,"percentile":0.143,"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).
