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-2024-41050 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-2024-41050/ (Markdown: https://insights.sbomify.com/CVE-2024-41050/index.md)","id":"CVE-2024-41050","markdown":"https://insights.sbomify.com/CVE-2024-41050/index.md","name":"CVE-2024-41050","record":{"aliases":["BELL-CVE-2024-41050","DEBIAN-CVE-2024-41050","GHSA-f68f-787f-7j6w","ROOT-OS-UBUNTU-2204-CVE-2024-41050","UBUNTU-CVE-2024-41050"],"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 the Linux kernel cachefiles module allows a malicious user to cause a system hang by reusing message IDs during object reopening.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ncachefiles: cyclic allocation of msg_id to avoid reuse\n\nReusing the msg_id after a maliciously completed reopen request may cause\na read request to remain unprocessed and result in a hung, as shown below:\n\n       t1       |      t2       |      t3\n-------------------------------------------------\ncachefiles_ondemand_select_req\n cachefiles_ondemand_object_is_close(A)\n cachefiles_ondemand_set_object_reopening(A)\n queue_work(fscache_object_wq, \u0026info-\u003ework)\n                ondemand_object_worker\n                 cachefiles_ondemand_init_object(A)\n                  cachefiles_ondemand_send_req(OPEN)\n                    // get msg_id 6\n                    wait_for_completion(\u0026req_A-\u003edone)\ncachefiles_ondemand_daemon_read\n // read msg_id 6 req_A\n cachefiles_ondemand_get_fd\n copy_to_user\n                                // Malicious completion msg_id 6\n                                copen 6,-1\n                                cachefiles_ondemand_copen\n                                 complete(\u0026req_A-\u003edone)\n                                 // will not set the object to close\n                                 // because ondemand_id \u0026\u0026 fd is valid.\n\n                // ondemand_object_worker() is done\n                // but the object is still reopening.\n\n                                // new open req_B\n                                cachefiles_ondemand_init_object(B)\n                                 cachefiles_ondemand_send_req(OPEN)\n                                 // reuse msg_id 6\nprocess_open_req\n copen 6,A.size\n // The expected failed copen was executed successfully\n\nExpect copen to fail, and when it does, it closes fd, which sets the\nobject to close, and then close triggers reopen again.
