{"id":"CVE-2026-97576","summary":"media: v4l2-ctrls: validate HEVC tile counts","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: v4l2-ctrls: validate HEVC tile counts\n\nThe stateless HEVC decoders read num_tile_columns_minus1 + 1 entries from\ncolumn_width_minus1[] and num_tile_rows_minus1 + 1 from row_height_minus1[]\nand use them as tile-loop bounds, but std_validate_compound() does not\nbound these u8 counts. Reject a V4L2_CTRL_TYPE_HEVC_PPS with tiling\nenabled whose tile counts exceed the uAPI array capacity, mirroring the\nexisting compound-control range checks.","modified":"2026-10-09T17:26:58.993229550Z","published":"2026-09-25T10:21:59.298Z","related":["openSUSE-SU-2026:12074-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97576.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/400cd78a63cc647412cf069c9851bdea2818340c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/724915535558b14c111ad8a498b896026dfe8d20"},{"type":"WEB","url":"https://git.kernel.org/stable/c/975e0180488966bb709092a52408604bd4f4edd9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9c0a718e24d4cd6d975f3df9740f968f62891a20"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ba1023d3a6d5d244d59f20c4ba6af4879ae08a9f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c7b1ef6dc57f4e57fe27cfdd3bf82033ed91ca34"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dc694a9929f7cb9c88ef91e45eb982b7bbe5a477"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97576.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97576"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"256fa3920874b0f1f4cb79ad6766493a22187153"},{"fixed":"9c0a718e24d4cd6d975f3df9740f968f62891a20"},{"fixed":"975e0180488966bb709092a52408604bd4f4edd9"},{"fixed":"724915535558b14c111ad8a498b896026dfe8d20"},{"fixed":"400cd78a63cc647412cf069c9851bdea2818340c"},{"fixed":"c7b1ef6dc57f4e57fe27cfdd3bf82033ed91ca34"},{"fixed":"ba1023d3a6d5d244d59f20c4ba6af4879ae08a9f"},{"fixed":"dc694a9929f7cb9c88ef91e45eb982b7bbe5a477"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-97576.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.5.0"},{"fixed":"5.15.222"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.111"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.53"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-97576.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
