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-2026-4930 in the wild and no public exploit code.\n\nAffected product: silabs.com Simplicity SDK. 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-2026-4930/ (Markdown: https://insights.sbomify.com/CVE-2026-4930/index.md)","id":"CVE-2026-4930","markdown":"https://insights.sbomify.com/CVE-2026-4930/index.md","name":"CVE-2026-4930","record":{"aliases":["GHSA-7ccr-fw66-p8jj"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Silicon Labs Simplicity SDK","requires_auth":"high_privilege","summary":"Attackers with code execution can weaken DPA countermeasures in the SYMCRYPTO engine, facilitating cryptographic key extraction via side-channel attacks.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Silabs","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:P/AC:L/AT:N/PR:H/UI:N/VC:H/VI:N/VA:N/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-331","name":"Insufficient Entropy"}],"description":"SYMCRYPTO is the SiXG301's host side hardware engine accessed by PSA crypto library that accelerates symmetric cryptographic operations (AES encryption/decryption and hashing).\n\nDPA Countermeasures on SYMCRYPTO can be weakened (reduced entropy) by forcing certain seed values if an attacker gains code execution capability on the impacted device.\n\n  *  Therefore, the keys loaded on SYMCRYPTO may be more vulnerable to extraction through DPA attacks than intended","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"DPA Countermeasures weakening on Series 3 devices","id":"CVE-2026-4930","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"CVE-2026-4931","id":"CVE-2026-4931"},"packages":[],"prev":{"headline":"Simple Hierarchical Select (Drupal 7) XSS in term-derived output","id":"CVE-2026-4929"},"products":["Simplicity SDK"],"published":"2026-06-25","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":"2026-06-25","vendors":["silabs.com"]},"summary":"Attackers with code execution can weaken DPA countermeasures in the SYMCRYPTO engine, facilitating cryptographic key extraction via side-channel attacks.","url":"https://insights.sbomify.com/CVE-2026-4930/"}
