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-2026-22985 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-2026-22985/ (Markdown: https://insights.sbomify.com/CVE-2026-22985/index.md)","id":"CVE-2026-22985","markdown":"https://insights.sbomify.com/CVE-2026-22985/index.md","name":"CVE-2026-22985","record":{"aliases":["BELL-CVE-2026-22985","DEBIAN-CVE-2026-22985","GHSA-gj4p-f535-7c3j","ROOT-OS-DEBIAN-13-CVE-2026-22985","ROOT-OS-UBUNTU-2404-CVE-2026-22985","UBUNTU-CVE-2026-22985"],"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 local attacker can crash the Linux kernel by disabling rxhash on an Intel idpf network interface before it is brought up.","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\nidpf: Fix RSS LUT NULL pointer crash on early ethtool operations\n\nThe RSS LUT is not initialized until the interface comes up, causing\nthe following NULL pointer crash when ethtool operations like rxhash on/off\nare performed before the interface is brought up for the first time.\n\nMove RSS LUT initialization from ndo_open to vport creation to ensure LUT\nis always available. This enables RSS configuration via ethtool before\nbringing the interface up. Simplify LUT management by maintaining all\nchanges in the driver's soft copy and programming zeros to the indirection\ntable when rxhash is disabled. Defer HW programming until the interface\ncomes up if it is down during rxhash and LUT configuration changes.\n\nSteps to reproduce:\n** Load idpf driver; interfaces will be created\n\tmodprobe idpf\n** Before bringing the interfaces up, turn rxhash off\n\tethtool -K eth2 rxhash off\n\n[89408.371875] BUG: kernel NULL pointer dereference, address: 0000000000000000\n[89408.371908] #PF: supervisor read access in kernel mode\n[89408.371924] #PF: error_code(0x0000) - not-present page\n[89408.371940] PGD 0 P4D 0\n[89408.371953] Oops: Oops: 0000 [#1] SMP NOPTI\n\u003csnip\u003e\n[89408.372052] RIP: 0010:memcpy_orig+0x16/0x130\n[89408.372310] Call Trace:\n[89408.372317]  \u003cTASK\u003e\n[89408.372326]  ? idpf_set_features+0xfc/0x180 [idpf]\n[89408.372363]  __netdev_update_features+0x295/0xde0\n[89408.372384]  ethnl_set_features+0x15e/0x460\n[89408.372406]  genl_family_rcv_msg_doit+0x11f/0x180\n[89408.372429]  genl_rcv_msg+0x1ad/0x2b0\n[89408.372446]  ? __pfx_ethnl_set_features+0x10/0x10\n[89408.372465]  ? __pfx_genl_rcv_msg+0x10/0x10\n[89408.372482]  netlink_rcv_skb+0x58/0x100\n[89408.372502]  genl_rcv+0x2c/0x50\n[89408.372516]  netlink_unicast+0x289/0x3e0\n[89408.372533]  netlink_sendmsg+0x215/0x440\n[89408.372551]  __sys_sendto+0x234/0x240\n[89408.372571]  __x64_sys_sendto+0x28/0x30\n[89408.372585]  x64_sys_call+0x1909/0x1da0\n[89408.372604]  do_syscall_64+0x7a/0xfa0\n[89408.373140]  ? clear_bhb_loop+0x60/0xb0\n[89408.373647]  entry_SYSCALL_64_after_hwframe+0x76/0x7e\n[89408.378887]  \u003c/TASK\u003e\n\u003csnip\u003e","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: Fix RSS LUT NULL pointer crash on early ethtool operations","id":"CVE-2026-22985","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"gpiolib: fix race condition for gdev-\u003esrcu","id":"CVE-2026-22986"},"packages":[],"prev":{"headline":"libceph: prevent potential out-of-bounds reads in handle_auth_done()","id":"CVE-2026-22984"},"products":["Linux"],"published":"2026-01-23","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 crash the Linux kernel by disabling rxhash on an Intel idpf network interface before it is brought up.","url":"https://insights.sbomify.com/CVE-2026-22985/"}
