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-2023-54104 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-2023-54104/ (Markdown: https://insights.sbomify.com/CVE-2023-54104/index.md)","id":"CVE-2023-54104","markdown":"https://insights.sbomify.com/CVE-2023-54104/index.md","name":"CVE-2023-54104","record":{"aliases":["BELL-CVE-2023-54104","DEBIAN-CVE-2023-54104","GHSA-39vf-5xqf-2xfv","UBUNTU-CVE-2023-54104"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","other"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel NAND driver","requires_auth":"low_privilege","summary":"An off-by-one error in the Linux kernel's FSL UPM NAND driver allows out-of-bounds memory access, potentially causing crashes or undefined behavior.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmtd: rawnand: fsl_upm: Fix an off-by one test in fun_exec_op()\n\n'op-cs' is copied in 'fun-\u003emchip_number' which is used to access the\n'mchip_offsets' and the 'rnb_gpio' arrays.\nThese arrays have NAND_MAX_CHIPS elements, so the index must be below this\nlimit.\n\nFix the sanity check in order to avoid the NAND_MAX_CHIPS value.
