{"id":"CVE-2026-46122","summary":"wifi: b43: enforce bounds check on firmware key index in b43_rx()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: b43: enforce bounds check on firmware key index in b43_rx()\n\nThe firmware-controlled key index in b43_rx() can exceed the dev-\u003ekey[]\narray size (58 entries). The existing B43_WARN_ON is non-enforcing in\nproduction builds, allowing an out-of-bounds read.\n\nMake the B43_WARN_ON check enforcing by dropping the frame when the\nfirmware returns an invalid key index.","modified":"2026-07-15T01:48:59.909714640Z","published":"2026-05-28T09:35:37.141Z","related":["openSUSE-SU-2026:10954-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46122.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/135cb49c9a42a02cceeac7b49ec03e267f7ed6d6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1e9e55cf66f0fa4799f4d86ef3aaba8e606b5c14"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1f4f78bf8549e6ac4f04fba4176854f3a6e0c332"},{"type":"WEB","url":"https://git.kernel.org/stable/c/219ba67e69e49681e48c822d6eaafb5def032f34"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3157ad40b084a8f3932da2641749ab45e99b933e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/765709720e6af9a178abc40244a8d1aa39ac4e71"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c3d7b90dc95020cd9282c4630e402fe224f7644e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d7029879bafdac2006c67553807d122283dc6cbf"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46122.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46122"},{"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":"e4d6b7951812d98417feb10784e400e253caf633"},{"fixed":"135cb49c9a42a02cceeac7b49ec03e267f7ed6d6"},{"fixed":"3157ad40b084a8f3932da2641749ab45e99b933e"},{"fixed":"765709720e6af9a178abc40244a8d1aa39ac4e71"},{"fixed":"c3d7b90dc95020cd9282c4630e402fe224f7644e"},{"fixed":"1e9e55cf66f0fa4799f4d86ef3aaba8e606b5c14"},{"fixed":"d7029879bafdac2006c67553807d122283dc6cbf"},{"fixed":"219ba67e69e49681e48c822d6eaafb5def032f34"},{"fixed":"1f4f78bf8549e6ac4f04fba4176854f3a6e0c332"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46122.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-2026-46122.json"}}],"schema_version":"1.7.5"}
