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-2023-54072 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-2023-54072/ (Markdown: https://insights.sbomify.com/CVE-2023-54072/index.md)","id":"CVE-2023-54072","markdown":"https://insights.sbomify.com/CVE-2023-54072/index.md","name":"CVE-2023-54072","record":{"aliases":["BELL-CVE-2023-54072","DEBIAN-CVE-2023-54072","GHSA-xx23-73hr-9p64","UBUNTU-CVE-2023-54072"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A race condition in Linux kernel ALSA PCM memory allocation allows local users to exceed memory limits, potentially causing denial of service.","user_interaction":"not_required","vuln_class":"race_condition"},"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\nALSA: pcm: Fix potential data race at PCM memory allocation helpers\n\nThe PCM memory allocation helpers have a sanity check against too many\nbuffer allocations.  However, the check is performed without a proper\nlock and the allocation isn't serialized; this allows user to allocate\nmore memories than predefined max size.\n\nPractically seen, this isn't really a big problem, as it's more or\nless some \"soft limit\" as a sanity check, and it's not possible to\nallocate unlimitedly.  But it's still better to address this for more\nconsistent behavior.\n\nThe patch covers the size check in do_alloc_pages() with the\ncard-\u003ememory_mutex, and increases the allocated size there for\npreventing the further overflow.
