{"id":"CVE-2026-119727","state":"PUBLISHED","title":"Gst-plugins-bad: gst-plugins-bad: h.265 sps scc palette predictor array overflow via integer underflow in bounds computation","description":"A flaw was found in GStreamer's gst-plugins-bad H.265 video parser. When parsing a specially crafted H.265 bitstream containing a Screen Content Coding (SCC) extension with certain palette predictor initializer settings, an integer underflow in the upper-bound computation allows the parser to accept an out-of-range value for the number of palette predictor entries. This causes the parser to write beyond the end of a fixed-size array, resulting in memory corruption and an application crash. Successful exploitation requires an attacker to provide a malformed H.265 media file to a vulnerable application, and is limited to a denial-of-service impact.","publishedAt":"2026-10-30T18:51:08.851Z","updatedAt":"2026-10-30T18:51:08.851Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","source":"redhat"},"assigner":"redhat","products":["Red Hat Red Hat Enterprise Linux 10","Red Hat Red Hat Enterprise Linux 7","Red Hat Red Hat Enterprise Linux 8","Red Hat Red Hat Enterprise Linux 9"],"affected":[{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 10","packageName":"gstreamer1-plugins-bad-free","defaultStatus":"affected","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","cpes":["cpe:/o:redhat:enterprise_linux:10"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 7","packageName":"gstreamer1-plugins-bad-free","defaultStatus":"unaffected","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","cpes":["cpe:/o:redhat:enterprise_linux:7"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 8","packageName":"gstreamer1-plugins-bad-free","defaultStatus":"unaffected","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","cpes":["cpe:/o:redhat:enterprise_linux:8"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 9","packageName":"gstreamer1-plugins-bad-free","defaultStatus":"affected","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","cpes":["cpe:/o:redhat:enterprise_linux:9"]}],"references":["https://access.redhat.com/security/cve/CVE-2026-119727","https://bugzilla.redhat.com/show_bug.cgi?id=2564118","https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/10902.patch","https://gstreamer.freedesktop.org/security/sa-2026-0012.html"],"weaknesses":["CWE-122"],"ingestedAt":"2026-10-30T19:00:06.316Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/119xxx/CVE-2026-119727.json","commit":"517ce08d82effc9f265e15e818f17b398c5280d9","baselineCommit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-119727","state":"PUBLISHED","datePublished":"2026-10-30T18:51:08.851Z","dateUpdated":"2026-10-30T18:51:08.851Z","assignerShortName":"redhat","assignerOrgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","dateReserved":"2026-10-30T15:05:36.023Z"},"containers":{"cna":{"title":"Gst-plugins-bad: gst-plugins-bad: h.265 sps scc palette predictor array overflow via integer underflow in bounds computation","descriptions":[{"lang":"en","value":"A flaw was found in GStreamer's gst-plugins-bad H.265 video parser.
