An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2024-52878 and fix it if it is affected.\n\nWhat it is: CVE-2024-52878 is a high-severity memory corruption vulnerability in Insyde Insydeh2o, published on 15 May 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-52878 in the wild and no public exploit code.\n\nAffected product: Insyde Insydeh2o. 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-2024-52878/ (Markdown: https://insights.sbomify.com/CVE-2024-52878/index.md)","id":"CVE-2024-52878","markdown":"https://insights.sbomify.com/CVE-2024-52878/index.md","name":"CVE-2024-52878","record":{"aliases":["GHSA-qc53-6pcv-3q2p"],"analysis":{"component_type":"hardware_firmware","fix_type":"upgrade","impacts":["other"],"network_reachable":"yes","non_default_config":false,"product_category":"InsydeH2O UEFI firmware","requires_auth":"none","summary":"A buffer over-read in the InsydeH2O UEFI firmware VariableRuntimeDxe driver allows attackers to potentially read sensitive memory or cause system instability.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"insydeh2o","vendor":"insyde"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-126","name":"Buffer Over-read"}],"description":"An issue was discovered in Insyde InsydeH2O kernel 5.2 before version 05.29.50, kernel 5.3 before version 05.38.50, kernel 5.4 before version 05.46.50, kernel 5.5 before version 05.54.50, kernel 5.6 before version 05.61.50, and kernel 5.7 before version 05.70.50.
