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-2024-50229 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-2024-50229/ (Markdown: https://insights.sbomify.com/CVE-2024-50229/index.md)","id":"CVE-2024-50229","markdown":"https://insights.sbomify.com/CVE-2024-50229/index.md","name":"CVE-2024-50229","record":{"aliases":["AZL-53067","AZL-53124","BELL-CVE-2024-50229","DEBIAN-CVE-2024-50229","GHSA-7h5p-3h8w-5629","UBUNTU-CVE-2024-50229"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel filesystem","requires_auth":"low_privilege","summary":"A deadlock in the nilfs2 filesystem can cause a system hang when creating symlinks, requiring a kernel patch to resolve.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-667","name":"Improper Locking"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnilfs2: fix potential deadlock with newly created symlinks\n\nSyzbot reported that page_symlink(), called by nilfs_symlink(), triggers\nmemory reclamation involving the filesystem layer, which can result in\ncircular lock dependencies among the reader/writer semaphore\nnilfs-\u003ens_segctor_sem, s_writers percpu_rwsem (intwrite) and the\nfs_reclaim pseudo lock.\n\nThis is because after commit 21fc61c73c39 (\"don't put symlink bodies in\npagecache into highmem\"), the gfp flags of the page cache for symbolic\nlinks are overwritten to GFP_KERNEL via inode_nohighmem().\n\nThis is not a problem for symlinks read from the backing device, because\nthe __GFP_FS flag is dropped after inode_nohighmem() is called.
