An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-68806 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-2025-68806/ (Markdown: https://insights.sbomify.com/CVE-2025-68806/index.md)","id":"CVE-2025-68806","markdown":"https://insights.sbomify.com/CVE-2025-68806/index.md","name":"CVE-2025-68806","record":{"aliases":["AZL-74312","BELL-CVE-2025-68806","DEBIAN-CVE-2025-68806","GHSA-4wfq-6xp5-vp47","ROOT-OS-DEBIAN-12-CVE-2025-68806","ROOT-OS-DEBIAN-13-CVE-2025-68806","ROOT-OS-UBUNTU-2204-CVE-2025-68806","ROOT-OS-UBUNTU-2404-CVE-2025-68806","UBUNTU-CVE-2025-68806"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel SMB server","requires_auth":"none","summary":"A buffer validation error in the Linux kernel's ksmbd SMB server allows attackers to trigger memory corruption via crafted Extended Attributes.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: fix buffer validation by including null terminator size in EA length\n\nThe smb2_set_ea function, which handles Extended Attributes (EA),\nwas performing buffer validation checks that incorrectly omitted the size\nof the null terminating character (+1 byte) for EA Name.\nThis patch fixes the issue by explicitly adding '+ 1' to EaNameLength where\nthe null terminator is expected to be present in the buffer, ensuring\nthe validation accurately reflects the total required buffer size.","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":"ksmbd: fix buffer validation by including null terminator size in EA length","id":"CVE-2025-68806","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":5,"next":{"headline":"block: fix race between wbt_enable_default and IO submission","id":"CVE-2025-68807"},"packages":[],"prev":{"headline":"fuse: fix io-uring list corruption for terminated non-committed requests","id":"CVE-2025-68805"},"products":["Linux"],"published":"2026-01-13","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":"2026-08-05","vendors":["Linux"]},"summary":"A buffer validation error in the Linux kernel's ksmbd SMB server allows attackers to trigger memory corruption via crafted Extended Attributes.","url":"https://insights.sbomify.com/CVE-2025-68806/"}
