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-2026-43630 in the wild and no public exploit code.\n\nAffected product: ggml-org llama.cpp. 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-2026-43630/ (Markdown: https://insights.sbomify.com/CVE-2026-43630/index.md)","id":"CVE-2026-43630","markdown":"https://insights.sbomify.com/CVE-2026-43630/index.md","name":"CVE-2026-43630","record":{"aliases":["DEBIAN-CVE-2026-43630","GHSA-27j8-r4f8-8v3x","UBUNTU-CVE-2026-43630"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"LLM inference library","requires_auth":"none","summary":"Attackers with write access to slot directories can trigger out-of-bounds reads to leak heap data and defeat ASLR in llama.cpp.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"llama.cpp","vendor":"ggml"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-209","name":"Generation of Error Message Containing Sensitive Information"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"llama.cpp builds b4882 before b8487 contain an out-of-bounds read vulnerability in the recurrent memory state restore path that allows attackers with write access to the slot save directory to read memory past the end of the allocated cells array.
