Reject a V4L2_CTRL_TYPE_AV1_FRAME whose\ntile_cols or tile_rows exceeds V4L2_AV1_MAX_TILE_COLS / _ROWS, or whose\nproduct exceeds V4L2_AV1_MAX_TILE_COUNT. A zero tile count is left to the\nconsuming driver so the zero-initialised control that existing userspace\nsubmits is still accepted.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/1afaf85c4990fb1e3168d0d6e99246a65e526f1b","https://git.kernel.org/stable/c/439058ced617fbb3febc017b9e93bb7387f309e0","https://git.kernel.org/stable/c/85df9fc79b07f1cc7c953f930ae7e675d0c1e820","https://git.kernel.org/stable/c/c4c88b5ba85685043d171e0e9c9d00a8cf6a89e8","https://git.kernel.org/stable/c/c8891da0186fe4c04bccbbd7d84b01a3c941ac7a"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-97575","score":0.00163,"percentile":0.05499,"date":"2026-10-25"},"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).
