Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-93812 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-2026-93812/ (Markdown: https://insights.sbomify.com/CVE-2026-93812/index.md)","id":"CVE-2026-93812","markdown":"https://insights.sbomify.com/CVE-2026-93812/index.md","name":"CVE-2026-93812","record":{"aliases":["AZL-103949","BELL-CVE-2026-93812","DEBIAN-CVE-2026-93812","GHSA-7f3p-w572-qm2q","UBUNTU-CVE-2026-93812"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A memory leak in the Linux kernel's ksmbd module allows attackers to cause a denial of service by triggering encoding errors.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: fix sd_ndr.data memory leak in ksmbd_vfs_set_sd_xattr\n\nndr_encode_v4_ntacl() allocates sd_ndr.data via kzalloc() at entry.\nIf any subsequent ndr_write_*() call returns error during encoding,\nthe allocated sd_ndr.data won't be freed and causes memory leak.\n\nMove kfree(sd_ndr.data) into out label to ensure the buffer gets\nreleased on all success and error return paths.","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 sd_ndr.data memory leak in ksmbd_vfs_set_sd_xattr","id":"CVE-2026-93812","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":6,"next":{"headline":"btrfs: tree-checker: validate INODE_REF's namelen","id":"CVE-2026-93813"},"packages":[],"prev":{"headline":"ksmbd: Fix acl.sd_buf memory leak and invalid sd_size error handling","id":"CVE-2026-93811"},"products":["Linux"],"published":"2026-09-24","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-03","vendors":["Linux"]},"summary":"A memory leak in the Linux kernel's ksmbd module allows attackers to cause a denial of service by triggering encoding errors.","url":"https://insights.sbomify.com/CVE-2026-93812/"}
