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-2024-53148 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2024-53148/ (Markdown: https://insights.sbomify.com/CVE-2024-53148/index.md)","id":"CVE-2024-53148","markdown":"https://insights.sbomify.com/CVE-2024-53148/index.md","name":"CVE-2024-53148","record":{"aliases":["BELL-CVE-2024-53148","DEBIAN-CVE-2024-53148","GHSA-pm9c-5p62-35cr","UBUNTU-CVE-2024-53148"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A flaw in the Linux kernel comedi driver allows partial memory mappings to persist on error, potentially leading to memory corruption and privilege escalation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"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\ncomedi: Flush partial mappings in error case\n\nIf some remap_pfn_range() calls succeeded before one failed, we still have\nbuffer pages mapped into the userspace page tables when we drop the buffer\nreference with comedi_buf_map_put(bm).
