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-2026-55093 exists.\n\nAffected packages and fixed versions:\n- tract-nnef (crates.io): affected all versions; fixed in 0.21.16\n- tract-nnef (crates.io): affected all versions; fixed in 0.21.16\n- tract-nnef (crates.io): affected from 0.0.0-0; fixed in 0.21.16, 0.22.2, 0.23.1\n- tract-nnef (crates.io): affected from 0.22.0; fixed in 0.22.2\n- tract-nnef (crates.io): affected from 0.22.0; fixed in 0.22.2\n- tract-nnef (crates.io): affected from 0.23.0; fixed in 0.23.1\n- tract-nnef (crates.io): affected from 0.23.0; fixed in 0.23.1\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-2026-55093/ (Markdown: https://insights.sbomify.com/CVE-2026-55093/index.md)","id":"CVE-2026-55093","markdown":"https://insights.sbomify.com/CVE-2026-55093/index.md","name":"CVE-2026-55093","record":{"aliases":["GHSA-x5mv-8wgw-29hg","RUSTSEC-2026-0217"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Rust inference library","requires_auth":"none","summary":"An integer overflow in the NNEF tensor parser allows attackers to read adjacent memory or crash the application when loading crafted models.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Tract is a tiny, no-nonsense, self-contained TensorFlow and ONNX inference toolkit. Prior to 0.21.16, 0.22.2, and 0.23.1, tract-nnef uses unchecked usize multiplication in nnef/src/tensors.rs read_tensor for attacker-controlled tensor dimensions, the allocation size, and the reported tensor length. Loading a crafted NNEF archive through model_for_path or model_for_read reaches the default DatLoader and can make the wrapped size check accept a small allocation while data/src/tensor.rs as_slice_unchecked creates a much larger logical slice. Model construction through as_uniform can then read beyond the heap allocation and disclose adjacent data, and later access can terminate the process with a segmentation fault. The affected dense numeric tensor path does not include the independently guarded bool, String, or block-quant paths, and no out-of-bounds write or code execution was demonstrated. This issue is fixed in versions 0.21.16, 0.22.2, and 0.23.1.","ecosystems":["crates.io"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"tract-nnef: integer overflow in NNEF `.dat` tensor parser yields an out-of-bounds read on model load","id":"CVE-2026-55093","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"integer_overflow","year":"2026"},"n_packages":7,"n_references":7,"next":{"headline":"Taskcluster: Unauthenticated remote code execution in `web-server` via GraphQL `filter` argument (sift `$where`)","id":"CVE-2026-55094"},"packages":[{"ecosystem":"crates.io","fixed":["0.21.16"],"introduced":["0"],"last_affected":[],"package":"tract-nnef","purl":null,"source":"GHSA-x5mv-8wgw-29hg"},{"ecosystem":"crates.io","fixed":["0.21.16"],"introduced":["0"],"last_affected":[],"package":"tract-nnef","purl":"pkg:cargo/tract-nnef","source":"GHSA-x5mv-8wgw-29hg"},{"ecosystem":"crates.io","fixed":["0.21.16","0.22.2","0.23.1"],"introduced":["0.0.0-0","0.22.0","0.23.0"],"last_affected":[],"package":"tract-nnef","purl":"pkg:cargo/tract-nnef","source":"RUSTSEC-2026-0217"},{"ecosystem":"crates.io","fixed":["0.22.2"],"introduced":["0.22.0"],"last_affected":[],"package":"tract-nnef","purl":null,"source":"GHSA-x5mv-8wgw-29hg"},{"ecosystem":"crates.io","fixed":["0.22.2"],"introduced":["0.22.0"],"last_affected":[],"package":"tract-nnef","purl":"pkg:cargo/tract-nnef","source":"GHSA-x5mv-8wgw-29hg"},{"ecosystem":"crates.io","fixed":["0.23.1"],"introduced":["0.23.0"],"last_affected":[],"package":"tract-nnef","purl":null,"source":"GHSA-x5mv-8wgw-29hg"},{"ecosystem":"crates.io","fixed":["0.23.1"],"introduced":["0.23.0"],"last_affected":[],"package":"tract-nnef","purl":"pkg:cargo/tract-nnef","source":"GHSA-x5mv-8wgw-29hg"}],"prev":{"headline":"Trivy: Path traversal via a crafted vulnerability database or other downloaded artifacts","id":"CVE-2026-55092"},"products":["tract"],"published":"2026-09-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"open","licence":"CC0 1.0","name":"RustSec","prefix":"RUSTSEC"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-09-14","vendors":["sonos"]},"summary":"An integer overflow in the NNEF tensor parser allows attackers to read adjacent memory or crash the application when loading crafted models.","url":"https://insights.sbomify.com/CVE-2026-55093/"}
