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-2026-97853 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- decimal (Hex): affected from 0.1.0; fixed in 3.1.2\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-2026-97853/ (Markdown: https://insights.sbomify.com/CVE-2026-97853/index.md)","id":"CVE-2026-97853","markdown":"https://insights.sbomify.com/CVE-2026-97853/index.md","name":"CVE-2026-97853","record":{"aliases":["EEF-CVE-2026-97853","GHSA-6c27-994x-c52f"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Elixir decimal library","requires_auth":"none","summary":"Attackers can cause denial of service by supplying large decimal place arguments, exhausting memory in applications using the Elixir decimal library.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"EEF","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-789","name":"Memory Allocation with Excessive Size Value"}],"description":"Memory Allocation with Excessive Size Value vulnerability in ericmj decimal allows Denial of Service.\n\nDecimal.round/3 builds the full result for the requested number of decimal places before the context precision (34 digits by default) is applied, so its cost grows with the places argument instead of with the size of the result. For positive places it appends places zero digits to the coefficient as a charlist before converting it to an integer, and for negative places it builds a charlist of -places zero digits. A single call such as Decimal.round(Decimal.new(\"1.5\"), -50_000_000) allocates about 5.5 GB of memory, which can exhaust available memory and get the BEAM VM killed. The oldest releases instead loop once per decimal place, consuming CPU in proportion to places.\n\nAny application that passes a user-supplied number of decimal places or scale to Decimal.round/2 or Decimal.round/3 without bounding it is exposed. The input limits added for CVE-2026-32686 do not cover the places argument.\n\nThis issue affects decimal: from 0.1.0 before 3.1.2.","ecosystems":["Hex"],"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":"Unbounded allocation in decimal Decimal.round/3 driven by the places argument enables DoS","id":"CVE-2026-97853","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Hex","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":1,"n_references":6,"next":{"headline":"Yamaha wireless LAN router NWR100 provided by Yamaha Corporation contains an OS command injection vulnerability.","id":"CVE-2026-97854"},"packages":[{"ecosystem":"Hex","fixed":["3.1.2"],"introduced":["0.1.0"],"last_affected":[],"package":"decimal","purl":"pkg:hex/decimal","source":"EEF-CVE-2026-97853"}],"prev":{"headline":"J4Care dcm4che Missing Authorization","id":"CVE-2026-97851"},"products":["decimal"],"published":"2026-10-10","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"Erlang Ecosystem Foundation","prefix":"EEF"},{"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":"2026-10-15","vendors":["ericmj"]},"summary":"Attackers can cause denial of service by supplying large decimal place arguments, exhausting memory in applications using the Elixir decimal library.","url":"https://insights.sbomify.com/CVE-2026-97853/"}
