An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-52687 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-2023-52687/ (Markdown: https://insights.sbomify.com/CVE-2023-52687/index.md)","id":"CVE-2023-52687","markdown":"https://insights.sbomify.com/CVE-2023-52687/index.md","name":"CVE-2023-52687","record":{"aliases":["BELL-CVE-2023-52687","DEBIAN-CVE-2023-52687","GHSA-vx2v-mjff-9hjf","UBUNTU-CVE-2023-52687"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel crypto driver","requires_auth":"none","summary":"Missing error handling in the Marvell Safexcel crypto driver can lead to a null pointer dereference and kernel crash if DMA mapping fails.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-252","name":"Unchecked Return Value"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ncrypto: safexcel - Add error handling for dma_map_sg() calls\n\nMacro dma_map_sg() may return 0 on error.
