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-2021-40154 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-40154/ (Markdown: https://insights.sbomify.com/CVE-2021-40154/index.md)","id":"CVE-2021-40154","markdown":"https://insights.sbomify.com/CVE-2021-40154/index.md","name":"CVE-2021-40154","record":{"aliases":["GHSA-f88h-2xxc-h4r4"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"NXP LPC55S69 MCU","requires_auth":"low_privilege","summary":"An attacker with physical access can read protected flash memory via a crafted USB request during ISP mode on NXP LPC55S69 devices.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"lpc55s69jbd100_firmware","vendor":"nxp"},{"product":"lpc55s69jbd64_firmware","vendor":"nxp"},{"product":"lpc55s69jev98_firmware","vendor":"nxp"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AC:L/AV:L/A:L/C:H/I:N/PR:L/S:U/UI:N","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"NXP LPC55S69 devices before A3 have a buffer over-read via a crafted wlength value in a GET Descriptor Configuration request during use of USB In-System Programming (ISP) mode.
