This may lead to OOB access for\nindex[] and other parameters.\n\nAdd a sanity check for the card index and warn/correct it if it's a\nvalue out of the range.","modified":"2026-09-18T18:26:38.030528025Z","published":"2026-09-11T19:42:31.160Z","related":["openSUSE-SU-2026:11805-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80966.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0048994854f3e9c57b7a754de43ef8da5818d140"},{"type":"WEB","url":"https://git.kernel.org/stable/c/0ce391090809d610647f424b9b1dc24aa2c546fd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3690ef20469d5959378260e2752f2314a2572913"},{"type":"WEB","url":"https://git.kernel.org/stable/c/45ea0707298798678a60ff861b695aea049a5469"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5d7ac5e9ee5ba76b567ace13b46075caf79dcca0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/64898e9bd8b7b229efa8642b85b56b326a6ec3dc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d7ef7890e3e35b4ba09e76fc6b72047a1599a5e8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e1ce8ad1009b1736b3044b3324350dcfdd516f42"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80966.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80966"},{"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":"757e119bf52b014b3181eed97b01f87a245b8ff9"},{"fixed":"45ea0707298798678a60ff861b695aea049a5469"},{"fixed":"5d7ac5e9ee5ba76b567ace13b46075caf79dcca0"},{"fixed":"0048994854f3e9c57b7a754de43ef8da5818d140"},{"fixed":"64898e9bd8b7b229efa8642b85b56b326a6ec3dc"},{"fixed":"0ce391090809d610647f424b9b1dc24aa2c546fd"},{"fixed":"d7ef7890e3e35b4ba09e76fc6b72047a1599a5e8"},{"fixed":"e1ce8ad1009b1736b3044b3324350dcfdd516f42"},{"fixed":"3690ef20469d5959378260e2752f2314a2572913"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-80966.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.21"},{"fixed":"5.10.270"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.221"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.188"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.109"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.50"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-80966.json"}}],"schema_version":"1.9.0"}
