Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-68098 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-2026-68098/ (Markdown: https://insights.sbomify.com/CVE-2026-68098/index.md)","id":"CVE-2026-68098","markdown":"https://insights.sbomify.com/CVE-2026-68098/index.md","name":"CVE-2026-68098","record":{"aliases":["BELL-CVE-2026-68098","DEBIAN-CVE-2026-68098","GHSA-v5fh-ff84-cfpv","UBUNTU-CVE-2026-68098"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel SMB server","requires_auth":"low_privilege","summary":"An out-of-bounds read in the Linux kernel ksmbd module allows attackers to inspect invalid memory or cause a crash during DACL processing.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: bound DACL dedup walk to copied ACEs\n\nset_ntacl_dacl() can stop copying ACEs before consuming the full input\nDACL when size accounting overflows.\n\nWhen that happens, num_aces reflects only the ACEs that were actually\ncopied into the output DACL, but set_posix_acl_entries_dacl() still\nreceives nt_num_aces and uses it to walk the existing ACE array during\ndedup.\n\nThat makes the dedup walk scan past the copied ACE array and inspect\nbuffer tail that does not contain valid ACEs.\n\nSplit the two meanings currently carried by the NT ACE count.
