It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-4280 in the wild and no public exploit code.\n\nAffected product: silabs.com GSDK. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2023-4280/ (Markdown: https://insights.sbomify.com/CVE-2023-4280/index.md)","id":"CVE-2023-4280","markdown":"https://insights.sbomify.com/CVE-2023-4280/index.md","name":"CVE-2023-4280","record":{"aliases":["GHSA-3rwq-pxmh-pw55"],"analysis":{"component_type":"hardware_firmware","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Silicon Labs Gecko SDK","requires_auth":"none","summary":"Attackers can access trusted memory regions from untrusted areas due to unvalidated input in the TrustZone implementation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Silabs","cpe":[{"product":"gecko_software_development_kit","vendor":"silabs"}],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"An unvalidated input in Silicon Labs TrustZone implementation in v4.3.x and earlier of the Gecko SDK allows an attacker to access the trusted region of memory from the untrusted region.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Unvalidated input in Silicon Labs TrustZone implementation leads to accessing Trusted memory region","id":"CVE-2023-4280","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Activity Log \u003c 2.8.8 - IP Spoofing","id":"CVE-2023-4281"},"packages":[],"prev":{"headline":"User Activity Log \u003c 1.6.7 - IP Spoofing","id":"CVE-2023-4279"},"products":["GSDK"],"published":"2024-01-02","related":[{"cvss_score":10,"headline":"Memory corruption in Gecko Platform","id":"CVE-2023-45318","kev_date_added":null,"published":"2024-02-20"},{"cvss_score":9.8,"headline":"Memory corruption in Gecko Platform","id":"CVE-2023-2686","kev_date_added":null,"published":"2023-06-15"},{"cvss_score":9,"headline":"Unvalidated input in Silicon Labs PSA Attestation service leads to secure memory access from non-secure memory","id":"CVE-2023-4020","kev_date_added":null,"published":"2023-12-15"},{"cvss_score":9,"headline":"Memory corruption in Cesium NET","id":"CVE-2023-25181","kev_date_added":null,"published":"2023-11-14"},{"cvss_score":9,"headline":"Memory corruption in Cesium NET","id":"CVE-2023-27882","kev_date_added":null,"published":"2023-11-14"},{"cvss_score":9,"headline":"Memory corruption in Cesium NET","id":"CVE-2023-28379","kev_date_added":null,"published":"2023-11-14"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-06-13","vendors":["silabs.com"]},"summary":"Attackers can access trusted memory regions from untrusted areas due to unvalidated input in the TrustZone implementation.","url":"https://insights.sbomify.com/CVE-2023-4280/"}
