Exploitation requires physical access to the device and logical access to the SPI bus.","state":0,"publishedAt":"2026-10-12T17:16:27.538+00:00","modifiedAt":"2026-10-15T18:04:54.02+00:00","affected":[{"ecosystem":"Vendor product","name":"LR1110 Transceiver","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Semtech\",\n                    \"product\": \"LR1110 Transceiver\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"0x0403\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"unaffected\",\n                            \"version\": \"A1_0303\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"},{"ecosystem":"Vendor product","name":"LR1110 Modem-e","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Semtech\",\n                    \"product\": \"LR1110 Modem-e\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"2.1.1\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"},{"ecosystem":"Vendor product","name":"LR1120 Transceiver","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Semtech\",\n                    \"product\": \"LR1120 Transceiver\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"0x0203\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"unaffected\",\n                            \"version\": \"A2_0101\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"},{"ecosystem":"Vendor product","name":"LR1121 Transceiver","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Semtech\",\n                    \"product\": \"LR1121 Transceiver\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"0x0105\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"unaffected\",\n                            \"version\": \"A3_0101\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"},{"ecosystem":"Vendor product","name":"LR1121 Modem-e","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Semtech\",\n                    \"product\": \"LR1121 Modem-e\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"2.1.1\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N/R:U/RE:M","score":5.2,"severity":"MEDIUM"}],"references":["https://www.semtech.com/company/security/security-bulletins/sem-psa-2026-002-lr11xx-security-advisory"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-6232","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-6232","identifiers":["CVE-2026-6232"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
