Use the bounded v4l2_hevc_pps_num_tile_columns() /\nv4l2_hevc_pps_num_tile_rows() helpers for the tile loops, and bail out of\nassemble_hw_pps() before indexing priv_tbl-\u003eparam_set[] with an\nout-of-range pic_parameter_set_id, so the writes stay within the hardware\ntables.","modified":"2026-09-26T03:48:29.680111623Z","published":"2026-09-25T10:22:01.832Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97580.json"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/03beb248d8a7bab30559a60d4df81f167e63b9e3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/81ad46bb33d8fd279aaa33af5296c648814c964b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97580.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97580"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"3595375c2301653d5440d54b396df03499686c20"},{"fixed":"03beb248d8a7bab30559a60d4df81f167e63b9e3"},{"fixed":"81ad46bb33d8fd279aaa33af5296c648814c964b"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-97580.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-97580.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"}]}
