It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-98648 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-2026-98648/ (Markdown: https://insights.sbomify.com/CVE-2026-98648/index.md)","id":"CVE-2026-98648","markdown":"https://insights.sbomify.com/CVE-2026-98648/index.md","name":"CVE-2026-98648","record":{"aliases":["BELL-CVE-2026-98648","DEBIAN-CVE-2026-98648","GHSA-88ff-f8f3-f4qh","UBUNTU-CVE-2026-98648"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"An out-of-bounds read in the Linux kernel s390 UV driver allows attackers to read memory or cause a crash when handling many secrets.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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\ns390/uv: Prevent potential out-of-bounds read\n\nWhen the system has more than 85 secrets, the uv_secret_list struct\narray only holds up to 85 items per page, resulting in an out of bounds\nread in find_secret_in_page if the targeted secret is in the next page\nor not stored at all.\n\nFix this by looping over the number of stored secrets which is the\nper sub-list count of stored secrets and not the overall count.","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":"s390/uv: Prevent potential out-of-bounds read","id":"CVE-2026-98648","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"KVM: s390: Fix race in _destroy_pages_crste()","id":"CVE-2026-98649"},"packages":[],"prev":{"headline":"bpf: Fix divide-by-zero in btf_struct_walk()","id":"CVE-2026-98647"},"products":["Linux"],"published":"2026-10-18","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":"2026-10-19","vendors":["Linux"]},"summary":"An out-of-bounds read in the Linux kernel s390 UV driver allows attackers to read memory or cause a crash when handling many secrets.","url":"https://insights.sbomify.com/CVE-2026-98648/"}
