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-2026-59857 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-2026-59857/ (Markdown: https://insights.sbomify.com/CVE-2026-59857/index.md)","id":"CVE-2026-59857","markdown":"https://insights.sbomify.com/CVE-2026-59857/index.md","name":"CVE-2026-59857","record":{"aliases":["ALPINE-CVE-2026-59857","BELL-CVE-2026-59857","CLSA-2026-1784189693","CLSA-2026-1784800448","DEBIAN-CVE-2026-59857","ECHO-835b-eaa6-823f","GHSA-m3hf-xcm3-xhm2","MINI-c24r-gj9j-9rw2","UBUNTU-CVE-2026-59857"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Vim text editor","requires_auth":"none","summary":"A boundary error in Vim's spell checker allows a stack buffer overflow, potentially crashing the editor when processing specific words with SAL rules.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"vim","vendor":"vim"}],"cvss":{"score":5.6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Vim is an open source, command line text editor. Prior to 9.2.0725, the single-byte branch of spell_soundfold_sal() in src/spell.c translates a word through a spell file's SAL sound-folding rules into a caller-owned result buffer, but its result writes are guarded with reslen \u003c MAXWLEN, allowing reslen to reach MAXWLEN before res[reslen] = NUL writes one byte past the end of the MAXWLEN-element stack buffer. A boundary-length word passed to soundfold(), or reached via sound-based spell suggestion while a SAL-based spell language is active under a non-multibyte 8-bit encoding, can corrupt the eval_soundfold() stack frame and crash the editor.
