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: There is no known exploitation of CVE-2022-0326 in the wild and no public exploit code.\n\nAffected product: mruby/mruby. 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-2022-0326/ (Markdown: https://insights.sbomify.com/CVE-2022-0326/index.md)","id":"CVE-2022-0326","markdown":"https://insights.sbomify.com/CVE-2022-0326/index.md","name":"CVE-2022-0326","record":{"aliases":["AZL-41829","GHSA-54p3-947h-6fpr","UBUNTU-CVE-2022-0326"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"mruby library","requires_auth":"none","summary":"A NULL pointer dereference in the mruby library allows attackers to cause a denial of service condition.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntrdev","cpe":[{"product":"mruby","vendor":"mruby"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"NULL Pointer Dereference in Homebrew mruby prior to 3.2.","ecosystems":[],"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":"NULL Pointer Dereference in mruby/mruby","id":"CVE-2022-0326","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2022"},"n_packages":0,"n_references":2,"next":{"headline":"Master Addons for Elementor \u003c 1.8.2 - Reflected Cross-Site Scripting","id":"CVE-2022-0327"},"packages":[],"prev":{"headline":"Buffer Overflow in Dhcp6relay in Software for Open Networking in the Cloud (SONiC)","id":"CVE-2022-0324"},"products":["mruby/mruby"],"published":"2022-01-21","related":[{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-6838","kev_date_added":null,"published":"2020-01-11"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-6839","kev_date_added":null,"published":"2020-01-11"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-6840","kev_date_added":null,"published":"2020-01-11"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2018-10199","kev_date_added":null,"published":"2018-04-18"},{"cvss_score":9.3,"headline":"Use-After-Free in str_escape in mruby/mruby in mruby/mruby","id":"CVE-2022-1212","kev_date_added":null,"published":"2022-04-05"},{"cvss_score":9.1,"headline":"NULL Pointer Dereference in mruby/mruby","id":"CVE-2021-4110","kev_date_added":null,"published":"2021-12-15"},{"cvss_score":8.4,"headline":"Out-of-bounds Read in mrb_get_args in mruby/mruby","id":"CVE-2022-1276","kev_date_added":null,"published":"2022-04-10"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-02","vendors":["mruby"]},"summary":"A NULL pointer dereference in the mruby library allows attackers to cause a denial of service condition.","url":"https://insights.sbomify.com/CVE-2022-0326/"}
