Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-89794 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-2026-89794/ (Markdown: https://insights.sbomify.com/CVE-2026-89794/index.md)","id":"CVE-2026-89794","markdown":"https://insights.sbomify.com/CVE-2026-89794/index.md","name":"CVE-2026-89794","record":{"aliases":["AZL-101355","BELL-CVE-2026-89794","DEBIAN-CVE-2026-89794","GHSA-69w5-4c2f-pfhh","UBUNTU-CVE-2026-89794"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"An attacker can read uninitialized kernel heap memory via ksmbd pipe read compound padding, potentially exposing sensitive data.","user_interaction":"not_required","vuln_class":"information_disclosure"},"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: zero pipe read compound padding\n\nCompound response handling extends the last response iov to an eight-byte\nboundary.\n\nsmb2_read_pipe() allocates only the payload size, so the alignment padding\ncan expose up to seven bytes of uninitialized kernel heap memory.\n\nAllocate the aligned size and clear the unused tail before pinning the\nresponse buffer.","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: zero pipe read compound padding","id":"CVE-2026-89794","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"PCI: Allow per function PCI slots to fix slot reset on s390","id":"CVE-2026-89795"},"packages":[],"prev":{"headline":"ublk: clear VM_MAYWRITE on read-only ublk char device mmap","id":"CVE-2026-89793"},"products":["Linux"],"published":"2026-09-16","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":"2026-10-21","vendors":["Linux"]},"summary":"An attacker can read uninitialized kernel heap memory via ksmbd pipe read compound padding, potentially exposing sensitive data.","url":"https://insights.sbomify.com/CVE-2026-89794/"}
