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-2023-53848 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-2023-53848/ (Markdown: https://insights.sbomify.com/CVE-2023-53848/index.md)","id":"CVE-2023-53848","markdown":"https://insights.sbomify.com/CVE-2023-53848/index.md","name":"CVE-2023-53848","record":{"aliases":["BELL-CVE-2023-53848","DEBIAN-CVE-2023-53848","GHSA-j393-rh49-r5p6","UBUNTU-CVE-2023-53848"],"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":"none","summary":"A deadlock in the Linux kernel's RAID5 cache module can cause a denial of service when exiting the log.","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\nmd/raid5-cache: fix a deadlock in r5l_exit_log()\n\nCommit b13015af94cf (\"md/raid5-cache: Clear conf-\u003elog after finishing\nwork\") introduce a new problem:\n\n// caller hold reconfig_mutex\nr5l_exit_log\n flush_work(\u0026log-\u003edisable_writeback_work)\n\t\t\tr5c_disable_writeback_async\n\t\t\t wait_event\n\t\t\t  /*\n\t\t\t   * conf-\u003elog is not NULL, and mddev_trylock()\n\t\t\t   * will fail, wait_event() can never pass.\n\t\t\t   */\n conf-\u003elog = NULL\n\nFix this problem by setting 'config-\u003elog' to NULL before wake_up() as it\nused to be, so that wait_event() from r5c_disable_writeback_async() can\nexist.
