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-2026-89952 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-2026-89952/ (Markdown: https://insights.sbomify.com/CVE-2026-89952/index.md)","id":"CVE-2026-89952","markdown":"https://insights.sbomify.com/CVE-2026-89952/index.md","name":"CVE-2026-89952","record":{"aliases":["AZL-101228","BELL-CVE-2026-89952","DEBIAN-CVE-2026-89952","GHSA-xvpp-cjh2-87mx","UBUNTU-CVE-2026-89952"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel NAND driver","requires_auth":"none","summary":"A missing bounds check in the Linux kernel NAND driver allows attackers with physical access to trigger memory corruption via malformed ONFI parameter pages.","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\nmtd: rawnand: validate ONFI extended parameter page sections\n\nnand_flash_detect_ext_param_page() allocates the length declared by the\nONFI parameter page, then treats the data as a fixed header followed by\nvariable-length sections.
