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-2023-54204 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-2023-54204/ (Markdown: https://insights.sbomify.com/CVE-2023-54204/index.md)","id":"CVE-2023-54204","markdown":"https://insights.sbomify.com/CVE-2023-54204/index.md","name":"CVE-2023-54204","record":{"aliases":["BELL-CVE-2023-54204","DEBIAN-CVE-2023-54204","GHSA-f722-q47q-2685","UBUNTU-CVE-2023-54204"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A missing return value check in the Sunplus MMC driver can cause a null pointer dereference and memory leak, leading to a denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"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\nmmc: sunplus: fix return value check of mmc_add_host()\n\nmmc_add_host() may return error, if we ignore its return value,\n1. the memory allocated in mmc_alloc_host() will be leaked\n2. null-ptr-deref will happen when calling mmc_remove_host()\nin remove function spmmc_drv_remove() because deleting not\nadded device.\n\nFix this by checking the return value of mmc_add_host().
