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-2025-38383 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-2025-38383/ (Markdown: https://insights.sbomify.com/CVE-2025-38383/index.md)","id":"CVE-2025-38383","markdown":"https://insights.sbomify.com/CVE-2025-38383/index.md","name":"CVE-2025-38383","record":{"aliases":["ALSA-2026:1178","BELL-CVE-2025-38383","DEBIAN-CVE-2025-38383","GHSA-pqhv-fc7x-qjmr","RHSA-2026:1178","RLSA-2026:1178","UBUNTU-CVE-2025-38383"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["other"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A data race in the Linux kernel's vmalloc subsystem can lead to inconsistent state during proc file reads, requiring a kernel patch.","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":4.7,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmm/vmalloc: fix data race in show_numa_info()\n\nThe following data-race was found in show_numa_info():\n\n==================================================================\nBUG: KCSAN: data-race in vmalloc_info_show / vmalloc_info_show\n\nread to 0xffff88800971fe30 of 4 bytes by task 8289 on cpu 0:\n show_numa_info mm/vmalloc.c:4936 [inline]\n vmalloc_info_show+0x5a8/0x7e0 mm/vmalloc.c:5016\n seq_read_iter+0x373/0xb40 fs/seq_file.c:230\n proc_reg_read_iter+0x11e/0x170 fs/proc/inode.c:299\n....\n\nwrite to 0xffff88800971fe30 of 4 bytes by task 8287 on cpu 1:\n show_numa_info mm/vmalloc.c:4934 [inline]\n vmalloc_info_show+0x38f/0x7e0 mm/vmalloc.c:5016\n seq_read_iter+0x373/0xb40 fs/seq_file.c:230\n proc_reg_read_iter+0x11e/0x170 fs/proc/inode.c:299\n....\n\nvalue changed: 0x0000008f -\u003e 0x00000000\n==================================================================\n\nAccording to this report,there is a read/write data-race because\nm-\u003eprivate is accessible to multiple CPUs.
