{"schema":"threatline.record/2","record":{"id":"CVE-2026-97577","aliases":[],"summary":"media: verisilicon: rockchip: reject AV1 frames exceeding the tile capacity","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: verisilicon: rockchip: reject AV1 frames exceeding the tile capacity\n\nrockchip_vpu981_av1_dec_set_tile_info() indexes the tile group entry\narray by tile1 * tile_cols + tile0, reading up to tile_cols * tile_rows\nentries, lays out one descriptor per tile in the AV1_MAX_TILES tile_info\nbuffer, and programs the real tile_cols / tile_rows into the hardware.\n\nThe tile group entry control is a dynamic array sized to the number of\nentries userspace submitted, independent of tile_cols / tile_rows, so a\nframe that claims more tiles than entries reads past the array. 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.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97577","source_modified_at":"2026-10-19T09:09:39.822Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"727a400686a2c0d25015c9e44916a59b72882f83","lessThan":"95ee48eb17c91bd4859b65e0a54e7722f370d0e5","status":"affected","versionType":"git"},{"version":"727a400686a2c0d25015c9e44916a59b72882f83","lessThan":"40029f7f35397853f8711d6fce1d90a4c7a01f8c","status":"affected","versionType":"git"},{"version":"727a400686a2c0d25015c9e44916a59b72882f83","lessThan":"a41babf528f70c9a82ed31cfb5fe19065910f7f0","status":"affected","versionType":"git"},{"version":"727a400686a2c0d25015c9e44916a59b72882f83","lessThan":"fd965369220cc160bb20a24991790814bfbab401","status":"affected","versionType":"git"},{"version":"727a400686a2c0d25015c9e44916a59b72882f83","lessThan":"367db8b23c26a913d76ed70457bbcd781c422b49","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97577","source_modified_at":"2026-10-19T09:09:39.822Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.5","status":"affected"},{"version":"0","lessThan":"6.5","status":"unaffected","versionType":"semver"},{"version":"6.6.158","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.111","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.7","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97577","source_modified_at":"2026-10-19T09:09:39.822Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"95ee48eb17c91bd4859b65e0a54e7722f370d0e5","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97577","source_modified_at":"2026-10-19T09:09:39.822Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"40029f7f35397853f8711d6fce1d90a4c7a01f8c","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97577","source_modified_at":"2026-10-19T09:09:39.822Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"367db8b23c26a913d76ed70457bbcd781c422b49","basis":"first unaffected version stated in the CVE record"}],"cvss":7.8,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00163,"percentile":0.05237,"score_date":"2026-10-23"},"published_at":"2026-09-25T10:21:59.950Z","modified_at":"2026-10-19T09:09:39.822Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97577","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:09:39.822Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97577","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/95ee48eb17c91bd4859b65e0a54e7722f370d0e5"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/40029f7f35397853f8711d6fce1d90a4c7a01f8c"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/a41babf528f70c9a82ed31cfb5fe19065910f7f0"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/fd965369220cc160bb20a24991790814bfbab401"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/367db8b23c26a913d76ed70457bbcd781c422b49"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-19T09:09:39.822Z","content_hash":"8b1176497d8c17e2f7c8514b61f595857502ff76c129b09d9583d6bac064a721"}}
