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-2025-22116 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-2025-22116/ (Markdown: https://insights.sbomify.com/CVE-2025-22116/index.md)","id":"CVE-2025-22116","markdown":"https://insights.sbomify.com/CVE-2025-22116/index.md","name":"CVE-2025-22116","record":{"aliases":["BELL-CVE-2025-22116","DEBIAN-CVE-2025-22116","GHSA-whxm-hh66-2gfx","ROOT-OS-DEBIAN-13-CVE-2025-22116","ROOT-OS-UBUNTU-2404-CVE-2025-22116","UBUNTU-CVE-2025-22116"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A missing error check in the idpf driver causes a kernel warning and potential crash when unregistering a failed network device.","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\nidpf: check error for register_netdev() on init\n\nCurrent init logic ignores the error code from register_netdev(),\nwhich will cause WARN_ON() on attempt to unregister it, if there was one,\nand there is no info for the user that the creation of the netdev failed.\n\nWARNING: CPU: 89 PID: 6902 at net/core/dev.c:11512 unregister_netdevice_many_notify+0x211/0x1a10\n...\n[ 3707.563641]  unregister_netdev+0x1c/0x30\n[ 3707.563656]  idpf_vport_dealloc+0x5cf/0xce0 [idpf]\n[ 3707.563684]  idpf_deinit_task+0xef/0x160 [idpf]\n[ 3707.563712]  idpf_vc_core_deinit+0x84/0x320 [idpf]\n[ 3707.563739]  idpf_remove+0xbf/0x780 [idpf]\n[ 3707.563769]  pci_device_remove+0xab/0x1e0\n[ 3707.563786]  device_release_driver_internal+0x371/0x530\n[ 3707.563803]  driver_detach+0xbf/0x180\n[ 3707.563816]  bus_remove_driver+0x11b/0x2a0\n[ 3707.563829]  pci_unregister_driver+0x2a/0x250\n\nIntroduce an error check and log the vport number and error code.\nOn removal make sure to check VPORT_REG_NETDEV flag prior to calling\nunregister and free on the netdev.\n\nAdd local variables for idx, vport_config and netdev for readability.","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":"idpf: check error for register_netdev() on init","id":"CVE-2025-22116","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":3,"next":{"headline":"ice: fix using untrusted value of pkt_len in ice_vc_fdir_parse_raw()","id":"CVE-2025-22117"},"packages":[],"prev":{"headline":"btrfs: fix block group refcount race in btrfs_create_pending_block_groups()","id":"CVE-2025-22115"},"products":["Linux"],"published":"2025-04-16","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":"2026-05-11","vendors":["Linux"]},"summary":"A missing error check in the idpf driver causes a kernel warning and potential crash when unregistering a failed network device.","url":"https://insights.sbomify.com/CVE-2025-22116/"}
