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-2025-3301 in the wild and no public exploit code.\n\nAffected product: silabs.com Series 2 SoCs and associated modules. 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-2025-3301/ (Markdown: https://insights.sbomify.com/CVE-2025-3301/index.md)","id":"CVE-2025-3301","markdown":"https://insights.sbomify.com/CVE-2025-3301/index.md","name":"CVE-2025-3301","record":{"aliases":["GHSA-h3wr-2jpv-p235"],"analysis":{"component_type":"hardware_firmware","fix_type":"workaround","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Silicon Labs Series 2 SoC","requires_auth":"none","summary":"Missing DPA countermeasures in Silicon Labs Series 2 SoCs allow attackers to potentially expose confidential keys via side-channel attacks.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Silabs","cpe":[],"cvss":{"score":1,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:P/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1255","name":"Comparison Logic is Vulnerable to Power Side-Channel Attacks"}],"description":"DPA countermeasures are unavailable for ECDH key agreement and EdDSA signing operations on Curve25519 and Curve448 on all Series 2 modules and SoCs due to a lack of hardware and software support.
