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-2026-32249 in the wild and no public exploit code.\n\nAffected product: Vim Vim. 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-2026-32249/ (Markdown: https://insights.sbomify.com/CVE-2026-32249/index.md)","id":"CVE-2026-32249","markdown":"https://insights.sbomify.com/CVE-2026-32249/index.md","name":"CVE-2026-32249","record":{"aliases":["ALPINE-CVE-2026-32249","AZL-79845","BELL-CVE-2026-32249","DEBIAN-CVE-2026-32249","ECHO-fb0d-f99a-50a5","GHSA-9phh-423r-778r","MGASA-2026-0055","UBUNTU-CVE-2026-32249"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Vim text editor","requires_auth":"none","summary":"A NULL pointer dereference in Vim's NFA regex engine allows attackers to cause a segmentation fault and crash the application via crafted regex patterns.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"vim","vendor":"vim"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"Vim is an open source, command line text editor. From 9.1.0011 to before 9.2.0137, Vim's NFA regex compiler, when encountering a collection containing a combining character as the endpoint of a character range (e.g. [0-0\\u05bb]), incorrectly emits the composing bytes of that character as separate NFA states. This corrupts the NFA postfix stack, resulting in NFA_START_COLL having a NULL out1 pointer. When nfa_max_width() subsequently traverses the compiled NFA to estimate match width for the look-behind assertion, it dereferences state-\u003eout1-\u003eout without a NULL check, causing a segmentation fault. This vulnerability is fixed in 9.2.0137.","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":"NFA regex engine NULL pointer dereference affects Vim \u003c 9.2.0137","id":"CVE-2026-32249","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"vim:vim","products":["vim:vim"],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"NamelessMC has Reflected Cross-Site Scripting (XSS) in id parameter of /index.php?route=/queries/user/","id":"CVE-2026-32250"},"packages":[],"prev":{"headline":"Parse Server: Account takeover via operator injection in authentication data identifier","id":"CVE-2026-32248"},"products":["vim"],"published":"2026-03-12","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-20703","kev_date_added":null,"published":"2023-06-20"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2017-6349","kev_date_added":null,"published":"2017-02-27"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2017-6350","kev_date_added":null,"published":"2017-02-27"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2017-5953","kev_date_added":null,"published":"2017-02-10"},{"cvss_score":9.3,"headline":"Command injection in n/a","id":"CVE-2008-3075","kev_date_added":null,"published":"2009-02-21"},{"cvss_score":9.3,"headline":"Command injection in n/a","id":"CVE-2008-3076","kev_date_added":null,"published":"2009-02-21"},{"cvss_score":9.3,"headline":"Command injection in n/a","id":"CVE-2008-6235","kev_date_added":null,"published":"2009-02-21"}],"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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-03-13","vendors":["vim"]},"summary":"A NULL pointer dereference in Vim's NFA regex engine allows attackers to cause a segmentation fault and crash the application via crafted regex patterns.","url":"https://insights.sbomify.com/CVE-2026-32249/"}
