| Summary |
Out-of-bounds write in H.266/VVC parser when parsing PPS tile slices |
| Date |
2026-05-11 |
| Affected Versions |
GStreamer gst-plugins-bad < 1.28.3 |
| IDs |
GStreamer-SA-2026-0026 |
Details
Out-of-bounds write in the H.266/VVC codec parser (gsth266parser) when parsing
picture partition syntax (PPS) tile slices. The parser did not validate that the
number of slices within a tile did not exceed the total number of slices in the
picture, allowing writes beyond the allocated slice height arrays.
Impact
A malicious third party could trigger an out-of-bounds write by providing a
crafted H.266/VVC video stream with invalid tile slice configuration, potentially
resulting in a crash, data corruption, or arbitrary code execution.
Solution
The gst-plugins-bad 1.28.3 release addresses the issue. People using older
versions of GStreamer should apply the patch and recompile.
