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-2025-38195 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-2025-38195/ (Markdown: https://insights.sbomify.com/CVE-2025-38195/index.md)","id":"CVE-2025-38195","markdown":"https://insights.sbomify.com/CVE-2025-38195/index.md","name":"CVE-2025-38195","record":{"aliases":["BELL-CVE-2025-38195","DEBIAN-CVE-2025-38195","GHSA-qffh-4j5f-8w7g","ROOT-OS-DEBIAN-12-CVE-2025-38195","UBUNTU-CVE-2025-38195"],"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 local attacker can trigger a kernel panic via madvise on LoongArch systems, causing a denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nLoongArch: Fix panic caused by NULL-PMD in huge_pte_offset()\n\nERROR INFO:\n\nCPU 25 Unable to handle kernel paging request at virtual address 0x0\n         ...\n Call Trace:\n [\u003c900000000023c30c\u003e] huge_pte_offset+0x3c/0x58\n [\u003c900000000057fd4c\u003e] hugetlb_follow_page_mask+0x74/0x438\n [\u003c900000000051fee8\u003e] __get_user_pages+0xe0/0x4c8\n [\u003c9000000000522414\u003e] faultin_page_range+0x84/0x380\n [\u003c9000000000564e8c\u003e] madvise_vma_behavior+0x534/0xa48\n [\u003c900000000056689c\u003e] do_madvise+0x1bc/0x3e8\n [\u003c9000000000566df4\u003e] sys_madvise+0x24/0x38\n [\u003c90000000015b9e88\u003e] do_syscall+0x78/0x98\n [\u003c9000000000221f18\u003e] handle_syscall+0xb8/0x158\n\nIn some cases, pmd may be NULL and rely on NULL as the return value for\nprocessing, so it is necessary to determine this situation here.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"LoongArch: Fix panic caused by NULL-PMD in huge_pte_offset()","id":"CVE-2025-38195","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"null_dereference","year":"2025"},"n_packages":0,"n_references":4,"next":{"headline":"io_uring/rsrc: validate buffer count with offset for cloning","id":"CVE-2025-38196"},"packages":[],"prev":{"headline":"jffs2: check that raw node were preallocated before writing summary","id":"CVE-2025-38194"},"products":["Linux"],"published":"2025-07-04","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-23","vendors":["Linux"]},"summary":"A local attacker can trigger a kernel panic via madvise on LoongArch systems, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2025-38195/"}
