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-2023-54311 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-2023-54311/ (Markdown: https://insights.sbomify.com/CVE-2023-54311/index.md)","id":"CVE-2023-54311","markdown":"https://insights.sbomify.com/CVE-2023-54311/index.md","name":"CVE-2023-54311","record":{"aliases":["BELL-CVE-2023-54311","DEBIAN-CVE-2023-54311","GHSA-78x5-gg4g-8mmw","UBUNTU-CVE-2023-54311"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A local attacker can cause a kernel deadlock in ext4 filesystems using inline data in nojournal mode, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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\next4: fix deadlock when converting an inline directory in nojournal mode\n\nIn no journal mode, ext4_finish_convert_inline_dir() can self-deadlock\nby calling ext4_handle_dirty_dirblock() when it already has taken the\ndirectory lock.
