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-2024-42040 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-2024-42040/ (Markdown: https://insights.sbomify.com/CVE-2024-42040/index.md)","id":"CVE-2024-42040","markdown":"https://insights.sbomify.com/CVE-2024-42040/index.md","name":"CVE-2024-42040","record":{"aliases":["DEBIAN-CVE-2024-42040","GHSA-xh96-vq46-m9ww","OESA-2026-1971","UBUNTU-CVE-2024-42040"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"U-Boot bootloader","requires_auth":"none","summary":"An attacker on the local network can leak up to 32 bytes of memory from U-Boot via crafted DHCP responses, potentially exposing sensitive data.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"u-boot","vendor":"denx"}],"cvss":{"score":8.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Buffer Overflow vulnerability in the net/bootp.c in DENEX U-Boot from its initial commit in 2002 (3861aa5) up to today on any platform allows an attacker on the local network to leak memory from four up to 32 bytes of memory stored behind the packet to the network depending on the later use of DHCP-provided parameters via crafted DHCP responses.","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":"Information disclosure in n/a","id":"CVE-2024-42040","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2024"},"n_packages":0,"n_references":2,"next":{"headline":"Code injection in n/a","id":"CVE-2024-42041"},"packages":[],"prev":{"headline":"Missing authorization in EMUI","id":"CVE-2024-42039"},"products":["n/a"],"published":"2024-08-23","related":[{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2022-34835","kev_date_added":null,"published":"2022-06-29"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2022-30767","kev_date_added":null,"published":"2022-05-16"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-8432","kev_date_added":null,"published":"2020-01-29"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2019-14192","kev_date_added":null,"published":"2019-07-31"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-14193","kev_date_added":null,"published":"2019-07-31"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-14194","kev_date_added":null,"published":"2019-07-31"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-14195","kev_date_added":null,"published":"2019-07-31"}],"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":"2024-11-20","vendors":["n/a"]},"summary":"An attacker on the local network can leak up to 32 bytes of memory from U-Boot via crafted DHCP responses, potentially exposing sensitive data.","url":"https://insights.sbomify.com/CVE-2024-42040/"}
