A frame\nthat claims more than AV1_MAX_TILES tiles also leaves the hardware\nprogrammed for more tiles than the descriptor buffer holds.\n\nReject both in prepare_run(): tile_cols * tile_rows must not exceed the\nsubmitted entry count or AV1_MAX_TILES. The entry count is read via\nv4l2_ctrl_find() (ctrl->elems). This mirrors the bound the mediatek AV1\ndecoder already enforces.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · updated 2026-09-29 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-97577.json)","depth":"twilight","depthScore":43,"depthScoreParts":{"impact":42.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":210990,"id":"CVE-2026-97577","ts":1790349121782,"field":"cvss","old":null,"new":"7.8"},{"seq":210989,"id":"CVE-2026-97577","ts":1790349121782,"field":"severity","old":"none","new":"high"}]}
