Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-3873 in the wild and no public exploit code.\n\nAffected product: silabs.com WiseConnect. 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-2025-3873/ (Markdown: https://insights.sbomify.com/CVE-2025-3873/index.md)","id":"CVE-2025-3873","markdown":"https://insights.sbomify.com/CVE-2025-3873/index.md","name":"CVE-2025-3873","record":{"aliases":["GHSA-5f47-2v24-g377"],"analysis":{"component_type":"hardware_firmware","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"SiWx91x crypto APIs","requires_auth":"low_privilege","summary":"A buffer overflow in Silicon Labs SiWx91x crypto APIs allows attackers to corrupt host application data or execute code via unchecked output buffer sizes.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Silabs","cpe":[],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:N/VC:L/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"The following APIs for the Silcon Labs SiWx91x prior to vesion 3.4.0 failed to check the size of the output buffer of the caller which could lead to data corruption on the host (Cortex-M4) application.\n\nsl_si91x_aes\nsl_si91x_gcm\nsl_si91x_ccm \nsl_si91x_sha","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":"Buffer overflow in Si91x crypto APIs","id":"CVE-2025-3873","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"WordPress Simple PayPal Shopping Cart \u003c= 5.1.3 - Insecure Direct Object Reference","id":"CVE-2025-3874"},"packages":[],"prev":{"headline":"Privilege escalation by altering payload in contact form","id":"CVE-2025-3872"},"products":["WiseConnect"],"published":"2025-07-25","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2025-07-25","vendors":["silabs.com"]},"summary":"A buffer overflow in Silicon Labs SiWx91x crypto APIs allows attackers to corrupt host application data or execute code via unchecked output buffer sizes.","url":"https://insights.sbomify.com/CVE-2025-3873/"}
