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-2026-93816 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2026-93816/ (Markdown: https://insights.sbomify.com/CVE-2026-93816/index.md)","id":"CVE-2026-93816","markdown":"https://insights.sbomify.com/CVE-2026-93816/index.md","name":"CVE-2026-93816","record":{"aliases":["AZL-104006","BELL-CVE-2026-93816","DEBIAN-CVE-2026-93816","GHSA-g6g4-c2jh-p7hg","UBUNTU-CVE-2026-93816"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel filesystem","requires_auth":"none","summary":"A corrupted f2fs image can cause out-of-bounds reads during inline dentry conversion, potentially leading to system crashes or code execution.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nf2fs: validate inline dentry name lengths before conversion\n\nInline dentry conversion copies names out of the inline dentry area\nbefore checking that each recorded name length fits in the available\nfilename slots.\n\nA corrupted image can therefore make the conversion path read past\nthe inline filename storage while building the regular dentry block.\n\nValidate each inline dentry name length against the inline filename\narea before copying it.","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":"f2fs: validate inline dentry name lengths before conversion","id":"CVE-2026-93816","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":7,"next":{"headline":"perf: Fix addr_filter_ranges lifetime","id":"CVE-2026-93817"},"packages":[],"prev":{"headline":"net: au1000: move free_irq out of the close-time spinlocked section","id":"CVE-2026-93815"},"products":["Linux"],"published":"2026-09-24","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-03","vendors":["Linux"]},"summary":"A corrupted f2fs image can cause out-of-bounds reads during inline dentry conversion, potentially leading to system crashes or code execution.","url":"https://insights.sbomify.com/CVE-2026-93816/"}
