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-2025-38357 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-2025-38357/ (Markdown: https://insights.sbomify.com/CVE-2025-38357/index.md)","id":"CVE-2025-38357","markdown":"https://insights.sbomify.com/CVE-2025-38357/index.md","name":"CVE-2025-38357","record":{"aliases":["BELL-CVE-2025-38357","GHSA-5g77-7644-h27q","UBUNTU-CVE-2025-38357"],"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 missing fix in the FUSE filesystem triggers a runtime warning during truncation, potentially causing system instability or denial of service.","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":7.8,"severity":"high","source":"cna","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\nfuse: fix runtime warning on truncate_folio_batch_exceptionals()\n\nThe WARN_ON_ONCE is introduced on truncate_folio_batch_exceptionals() to\ncapture whether the filesystem has removed all DAX entries or not.\n\nAnd the fix has been applied on the filesystem xfs and ext4 by the commit\n0e2f80afcfa6 (\"fs/dax: ensure all pages are idle prior to filesystem\nunmount\").\n\nApply the missed fix on filesystem fuse to fix the runtime warning:\n\n[    2.011450] ------------[ cut here ]------------\n[    2.011873] WARNING: CPU: 0 PID: 145 at mm/truncate.c:89 truncate_folio_batch_exceptionals+0x272/0x2b0\n[    2.012468] Modules linked in:\n[    2.012718] CPU: 0 UID: 1000 PID: 145 Comm: weston Not tainted 6.16.0-rc2-WSL2-STABLE #2 PREEMPT(undef)\n[    2.013292] RIP: 0010:truncate_folio_batch_exceptionals+0x272/0x2b0\n[    2.013704] Code: 48 63 d0 41 29 c5 48 8d 1c d5 00 00 00 00 4e 8d 6c 2a 01 49 c1 e5 03 eb 09 48 83 c3 08 49 39 dd 74 83 41 f6 44 1c 08 01 74 ef \u003c0f\u003e 0b 49 8b 34 1e 48 89 ef e8 10 a2 17 00 eb df 48 8b 7d 00 e8 35\n[    2.014845] RSP: 0018:ffffa47ec33f3b10 EFLAGS: 00010202\n[    2.015279] RAX: 0000000000000000 RBX: 0000000000000000 RCX: 0000000000000000\n[    2.015884] RDX: 0000000000000000 RSI: ffffa47ec33f3ca0 RDI: ffff98aa44f3fa80\n[    2.016377] RBP: ffff98aa44f3fbf0 R08: ffffa47ec33f3ba8 R09: 0000000000000000\n[    2.016942] R10: 0000000000000001 R11: 0000000000000000 R12: ffffa47ec33f3ca0\n[    2.017437] R13: 0000000000000008 R14: ffffa47ec33f3ba8 R15: 0000000000000000\n[    2.017972] FS:  000079ce006afa40(0000) GS:ffff98aade441000(0000) knlGS:0000000000000000\n[    2.018510] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[    2.018987] CR2: 000079ce03e74000 CR3: 000000010784f006 CR4: 0000000000372eb0\n[    2.019518] Call Trace:\n[    2.019729]  \u003cTASK\u003e\n[    2.019901]  truncate_inode_pages_range+0xd8/0x400\n[    2.020280]  ?
