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.","state":0,"publishedAt":"2026-10-18T15:44:12.196+00:00","modifiedAt":"2026-10-19T09:23:26.505+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/iio/proximity/aw96103.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"07b241262dcad07671c444ca955903325de28e9e\",\n                            \"lessThan\": \"4a9b9f2d4e26589afd0ac099c8e5593170dd5ac7\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"07b241262dcad07671c444ca955903325de28e9e\",\n                            \"lessThan\": \"6501b032be217ecf47e793b78a05078cf0b604ad\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"07b241262dcad07671c444ca955903325de28e9e\",\n                            \"lessThan\": \"815ae0b73b69ace207b6bbf7ef428b06491c3ddb\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"07b241262dcad07671c444ca955903325de28e9e\",\n                            \"lessThan\": \"1a7c522a35477d70320bd64aba8e9de0c1058c6f\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/iio/proximity/aw96103.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.12\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.12\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.12.113\",\n                            \"lessThanOrEqual\": \"6.12.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.56\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.10\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/4a9b9f2d4e26589afd0ac099c8e5593170dd5ac7","https://git.kernel.org/stable/c/6501b032be217ecf47e793b78a05078cf0b604ad","https://git.kernel.org/stable/c/815ae0b73b69ace207b6bbf7ef428b06491c3ddb","https://git.kernel.org/stable/c/1a7c522a35477d70320bd64aba8e9de0c1058c6f"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-98658","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-98658","identifiers":["CVE-2026-98658"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
