The existing B43legacy_WARN_ON is\nnon-enforcing in production builds, allowing an out-of-bounds read of\ndev-\u003ekey[].\n\nMake the check enforcing by dropping the frame for invalid indices.","modified":"2026-07-21T09:59:33.481401271Z","published":"2026-05-28T09:36:18.946Z","related":["SUSE-SU-2026:3130-1","openSUSE-SU-2026:10954-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46163.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1baaeb6adecb9691748c0253dab6ddd19a2b4e9e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4242db36de99de734cc1f60e5edd86cda7e598c6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6ee946077607d7783ae6709a899213fc4fe08f35"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9d1bc155802943e92c57a5fb923d23edfbf0b525"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a035766f970bde2d4298346a31a80685be5c0205"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a92bd0503df2488f2cc040f329ebccff1c1934cb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/df805c1d085b7a96077f0964185764c87060950d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fdd4e51979f42ca8b1ab7e6176b607e1caabf2a5"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46163.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46163"},{"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":"75388acd0cd827dc1498043daa7d1c760902cd67"},{"fixed":"a92bd0503df2488f2cc040f329ebccff1c1934cb"},{"fixed":"df805c1d085b7a96077f0964185764c87060950d"},{"fixed":"4242db36de99de734cc1f60e5edd86cda7e598c6"},{"fixed":"1baaeb6adecb9691748c0253dab6ddd19a2b4e9e"},{"fixed":"6ee946077607d7783ae6709a899213fc4fe08f35"},{"fixed":"9d1bc155802943e92c57a5fb923d23edfbf0b525"},{"fixed":"fdd4e51979f42ca8b1ab7e6176b607e1caabf2a5"},{"fixed":"a035766f970bde2d4298346a31a80685be5c0205"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46163.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.24"},{"fixed":"5.10.258"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.209"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.175"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.140"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.88"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.30"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46163.json"}}],"schema_version":"1.7.5"}
