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-2024-57917 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-2024-57917/ (Markdown: https://insights.sbomify.com/CVE-2024-57917/index.md)","id":"CVE-2024-57917","markdown":"https://insights.sbomify.com/CVE-2024-57917/index.md","name":"CVE-2024-57917","record":{"aliases":["BELL-CVE-2024-57917","DEBIAN-CVE-2024-57917","GHSA-6w35-m3mc-pf7x","UBUNTU-CVE-2024-57917"],"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 topology subsystem can cause a kernel warning and potential denial of service during CPU hotplugging.","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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ntopology: Keep the cpumask unchanged when printing cpumap\n\nDuring fuzz testing, the following warning was discovered:\n\n different return values (15 and 11) from vsnprintf(\"%*pbl\n \", ...)\n\n test:keyward is WARNING in kvasprintf\n WARNING: CPU: 55 PID: 1168477 at lib/kasprintf.c:30 kvasprintf+0x121/0x130\n Call Trace:\n  kvasprintf+0x121/0x130\n  kasprintf+0xa6/0xe0\n  bitmap_print_to_buf+0x89/0x100\n  core_siblings_list_read+0x7e/0xb0\n  kernfs_file_read_iter+0x15b/0x270\n  new_sync_read+0x153/0x260\n  vfs_read+0x215/0x290\n  ksys_read+0xb9/0x160\n  do_syscall_64+0x56/0x100\n  entry_SYSCALL_64_after_hwframe+0x78/0xe2\n\nThe call trace shows that kvasprintf() reported this warning during the\nprinting of core_siblings_list. kvasprintf() has several steps:\n\n (1) First, calculate the length of the resulting formatted string.\n\n (2) Allocate a buffer based on the returned length.\n\n (3) Then, perform the actual string formatting.\n\n (4) Check whether the lengths of the formatted strings returned in\n     steps (1) and (2) are consistent.\n\nIf the core_cpumask is modified between steps (1) and (3), the lengths\nobtained in these two steps may not match.
