It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-33298 exists.\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-2026-33298/ (Markdown: https://insights.sbomify.com/CVE-2026-33298/index.md)","id":"CVE-2026-33298","markdown":"https://insights.sbomify.com/CVE-2026-33298/index.md","name":"CVE-2026-33298","record":{"aliases":["DEBIAN-CVE-2026-33298","GHSA-96jg-mvhq-q7q7","UBUNTU-CVE-2026-33298"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"LLM inference library","requires_auth":"none","summary":"An integer overflow in llama.cpp allows attackers to trigger a heap buffer overflow via crafted GGUF files, potentially leading to remote code execution.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"llama.cpp","vendor":"ggml"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"},{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"llama.cpp is an inference of several LLM models in C/C++. Prior to b7824, an integer overflow vulnerability in the `ggml_nbytes` function allows an attacker to bypass memory validation by crafting a GGUF file with specific tensor dimensions. This causes `ggml_nbytes` to return a significantly smaller size than required (e.g., 4MB instead of Exabytes), leading to a heap-based buffer overflow when the application subsequently processes the tensor. This vulnerability allows potential Remote Code Execution (RCE) via memory corruption. b7824 contains a fix.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"llama.cpp has a Heap Buffer Overflow via Integer Overflow in GGUF Tensor Parsing","id":"CVE-2026-33298","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"OpenEMR has Stored XSS in patient encounter Eye Exam form answers","id":"CVE-2026-33299"},"packages":[],"prev":{"headline":"AVideo has an IDOR - Any Admin Can Set Another User's Channel Password via setPassword.json.php","id":"CVE-2026-33297"},"products":["llama.cpp"],"published":"2026-03-24","related":[{"cvss_score":10,"headline":"llama.cpp allows write-what-where in rpc_server::set_tensor","id":"CVE-2024-42479","kev_date_added":null,"published":"2024-08-12"},{"cvss_score":9.8,"headline":"llama.cpp: Unauthenticated RCE via GRAPH_COMPUTE buffer=0 bypass in llama.cpp RPC backend","id":"CVE-2026-34159","kev_date_added":null,"published":"2026-04-01"},{"cvss_score":9.2,"headline":"llama.cpp b4882–b9058 Buffer Overflow in KV Cache State Restore","id":"CVE-2026-43629","kev_date_added":null,"published":"2026-08-06"},{"cvss_score":9.2,"headline":"llama.cpp b7492–b9060 Use-After-Free RCE via llama-server","id":"CVE-2026-43631","kev_date_added":null,"published":"2026-08-06"},{"cvss_score":9.2,"headline":"llama.cpp b7492–b9060 Use-After-Free in Tokenization Endpoints","id":"CVE-2026-43632","kev_date_added":null,"published":"2026-08-06"},{"cvss_score":8.8,"headline":"llama.cpp has Out-of-bounds Write in llama-server","id":"CVE-2026-21869","kev_date_added":null,"published":"2026-01-07"},{"cvss_score":8.8,"headline":"llama.cpp Vulnerable to Buffer Overflow via Malicious GGUF Model","id":"CVE-2025-49847","kev_date_added":null,"published":"2025-06-17"}],"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":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-25","vendors":["ggml-org"]},"summary":"An integer overflow in llama.cpp allows attackers to trigger a heap buffer overflow via crafted GGUF files, potentially leading to remote code execution.","url":"https://insights.sbomify.com/CVE-2026-33298/"}
