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-2026-3503 in the wild and no public exploit code.\n\nAffected product: Wolfssl Wolfssl. 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-2026-3503/ (Markdown: https://insights.sbomify.com/CVE-2026-3503/index.md)","id":"CVE-2026-3503","markdown":"https://insights.sbomify.com/CVE-2026-3503/index.md","name":"CVE-2026-3503","record":{"aliases":["DEBIAN-CVE-2026-3503","GHSA-pgc5-r6cv-2825","JLSEC-2026-705","UBUNTU-CVE-2026-3503"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"wolfSSL cryptographic library","requires_auth":"none","summary":"Physical attackers can compromise cryptographic keys in wolfSSL on ARM Cortex-M devices via fault injection attacks during post-quantum operations.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wolfSSL","cpe":[{"product":"wolfssl","vendor":"wolfssl"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:P/AC:H/AT:P/PR:N/UI:N/VC:H/VI:L/VA:N/SC:L/SI:L/SA:N/U:Amber","version":"4.0"},"cwes":[{"id":"CWE-335","name":"Incorrect Usage of Seeds in Pseudo-Random Number Generator (PRNG)"}],"description":"Protection mechanism failure in wolfCrypt post-quantum implementations (ML-KEM and ML-DSA) in wolfSSL on ARM Cortex-M microcontrollers allows a physical attacker to compromise key material and/or cryptographic outcomes via induced transient faults that corrupt or redirect seed/pointer values during Keccak-based expansion.\n\nThis issue affects wolfSSL (wolfCrypt): commit hash d86575c766e6e67ef93545fa69c04d6eb49400c6.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Fault injection attack with ML-DSA and ML-KEM on ARM","id":"CVE-2026-3503","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"wolfssl:wolfssl","products":["wolfssl:wolfssl"],"type":"weak_cryptography","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in Dokan: AI Powered WooCommerce Multivendor Marketplace Solution – Build Your Own Amazon, eBay, Etsy","id":"CVE-2026-3504"},"packages":[],"prev":{"headline":"TrueConf Client Download of Code Without Integrity Check","id":"CVE-2026-3502"},"products":["wolfSSL (wolfCrypt)"],"published":"2026-03-19","related":[{"cvss_score":10,"headline":"Buffer overread in domain name matching","id":"CVE-2024-5991","kev_date_added":null,"published":"2024-08-27"},{"cvss_score":9.8,"headline":"Security feature bypass in n/a","id":"CVE-2021-37155","kev_date_added":null,"published":"2021-07-21"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-36177","kev_date_added":null,"published":"2021-01-06"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2014-2896","kev_date_added":null,"published":"2020-01-28"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2014-2897","kev_date_added":null,"published":"2020-01-28"},{"cvss_score":9.8,"headline":"Information disclosure in n/a","id":"CVE-2014-2898","kev_date_added":null,"published":"2020-01-28"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-16748","kev_date_added":null,"published":"2019-09-24"}],"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":"2026-03-19","vendors":["wolfSSL Inc."]},"summary":"Physical attackers can compromise cryptographic keys in wolfSSL on ARM Cortex-M devices via fault injection attacks during post-quantum operations.","url":"https://insights.sbomify.com/CVE-2026-3503/"}
