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-2025-71233 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-2025-71233/ (Markdown: https://insights.sbomify.com/CVE-2025-71233/index.md)","id":"CVE-2025-71233","markdown":"https://insights.sbomify.com/CVE-2025-71233/index.md","name":"CVE-2025-71233","record":{"aliases":["AZL-77951","BELL-CVE-2025-71233","DEBIAN-CVE-2025-71233","GHSA-78xc-39m5-v2c6","ROOT-OS-DEBIAN-11-CVE-2025-71233","ROOT-OS-DEBIAN-12-CVE-2025-71233","ROOT-OS-UBUNTU-2204-CVE-2025-71233","ROOT-OS-UBUNTU-2404-CVE-2025-71233","UBUNTU-CVE-2025-71233"],"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 crash via a race condition in PCI endpoint configfs operations, causing 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":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nPCI: endpoint: Avoid creating sub-groups asynchronously\n\nThe asynchronous creation of sub-groups by a delayed work could lead to a\nNULL pointer dereference when the driver directory is removed before the\nwork completes.\n\nThe crash can be easily reproduced with the following commands:\n\n  # cd /sys/kernel/config/pci_ep/functions/pci_epf_test\n  # for i in {1..20}; do mkdir test \u0026\u0026 rmdir test; done\n\n  BUG: kernel NULL pointer dereference, address: 0000000000000088\n  ...\n  Call Trace:\n   configfs_register_group+0x3d/0x190\n   pci_epf_cfs_work+0x41/0x110\n   process_one_work+0x18f/0x350\n   worker_thread+0x25a/0x3a0\n\nFix this issue by using configfs_add_default_group() API which does not\nhave the deadlock problem as configfs_register_group() and does not require\nthe delayed work handler.\n\n[mani: slightly reworded the description and added stable list]","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":"PCI: endpoint: Avoid creating sub-groups asynchronously","id":"CVE-2025-71233","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":7,"next":{"headline":"wifi: rtl8xxxu: fix slab-out-of-bounds in rtl8xxxu_sta_add","id":"CVE-2025-71234"},"packages":[],"prev":{"headline":"scsi: qla2xxx: Free sp in error path to fix system crash","id":"CVE-2025-71232"},"products":["Linux"],"published":"2026-02-18","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A local attacker can trigger a kernel crash via a race condition in PCI endpoint configfs operations, causing denial of service.","url":"https://insights.sbomify.com/CVE-2025-71233/"}
