{"id":"CVE-2026-98658","summary":"iio: proximity: aw96103: validate firmware data length","details":"In the Linux kernel, the following vulnerability has been resolved:\n\niio: proximity: aw96103: validate firmware data length\n\nThe firmware parser reads a length from the binary header and then uses\nit to walk six-byte register/value entries. A truncated firmware image\ncan make the parser read beyond the copied firmware buffer. A value\nsmaller than the four-byte count field also underflows, producing a very\nlarge length.\n\nRead the little-endian field with get_unaligned_le32(), as previously\nproposed by David Lechner. Validate the header size, reject an\nunderflowed length, ensure the resulting payload is contained in the\nfirmware image, and require it to contain whole register/value entries.","modified":"2026-10-19T02:46:01.171490096Z","published":"2026-10-18T15:44:12.196Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98658.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/1a7c522a35477d70320bd64aba8e9de0c1058c6f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4a9b9f2d4e26589afd0ac099c8e5593170dd5ac7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6501b032be217ecf47e793b78a05078cf0b604ad"},{"type":"WEB","url":"https://git.kernel.org/stable/c/815ae0b73b69ace207b6bbf7ef428b06491c3ddb"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98658.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98658"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"07b241262dcad07671c444ca955903325de28e9e"},{"fixed":"4a9b9f2d4e26589afd0ac099c8e5593170dd5ac7"},{"fixed":"6501b032be217ecf47e793b78a05078cf0b604ad"},{"fixed":"815ae0b73b69ace207b6bbf7ef428b06491c3ddb"},{"fixed":"1a7c522a35477d70320bd64aba8e9de0c1058c6f"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98658.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.12.0"},{"fixed":"6.12.113"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.56"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98658.json"}}],"schema_version":"1.9.0"}
