The event data passed to\ndell_wmi_process_key() is already parsed, so \"buffer\" already\nstarts after those two fields.\n\nUse the correct index for accessing the first data field to avoid\na potential buffer overread.","modified":"2026-09-18T03:48:44.312185319Z","published":"2026-09-17T16:11:32.609Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93129.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/392c19faec6bf4cb72fb02322e2a61e198dd8f72"},{"type":"WEB","url":"https://git.kernel.org/stable/c/adfd6846bea13667ff28f8aaf00c32fbd69825ab"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93129.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93129"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5fbd827eb9c224c33a5f263ee543a75fe957faa3"},{"fixed":"392c19faec6bf4cb72fb02322e2a61e198dd8f72"},{"fixed":"adfd6846bea13667ff28f8aaf00c32fbd69825ab"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93129.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-93129.json"}}],"schema_version":"1.9.0"}
