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-2022-48974 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-2022-48974/ (Markdown: https://insights.sbomify.com/CVE-2022-48974/index.md)","id":"CVE-2022-48974","markdown":"https://insights.sbomify.com/CVE-2022-48974/index.md","name":"CVE-2022-48974","record":{"aliases":["DEBIAN-CVE-2022-48974","GHSA-g3gx-vxgx-5xvc","UBUNTU-CVE-2022-48974"],"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 bug in the Linux kernel netfilter conntrack module causes a kernel panic when handling invalid extension data, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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\nnetfilter: conntrack: fix using __this_cpu_add in preemptible\n\nCurrently in nf_conntrack_hash_check_insert(), when it fails in\nnf_ct_ext_valid_pre/post(), NF_CT_STAT_INC() will be called in the\npreemptible context, a call trace can be triggered:\n\n   BUG: using __this_cpu_add() in preemptible [00000000] code: conntrack/1636\n   caller is nf_conntrack_hash_check_insert+0x45/0x430 [nf_conntrack]\n   Call Trace:\n    \u003cTASK\u003e\n    dump_stack_lvl+0x33/0x46\n    check_preemption_disabled+0xc3/0xf0\n    nf_conntrack_hash_check_insert+0x45/0x430 [nf_conntrack]\n    ctnetlink_create_conntrack+0x3cd/0x4e0 [nf_conntrack_netlink]\n    ctnetlink_new_conntrack+0x1c0/0x450 [nf_conntrack_netlink]\n    nfnetlink_rcv_msg+0x277/0x2f0 [nfnetlink]\n    netlink_rcv_skb+0x50/0x100\n    nfnetlink_rcv+0x65/0x144 [nfnetlink]\n    netlink_unicast+0x1ae/0x290\n    netlink_sendmsg+0x257/0x4f0\n    sock_sendmsg+0x5f/0x70\n\nThis patch is to fix it by changing to use NF_CT_STAT_INC_ATOMIC() for\nnf_ct_ext_valid_pre/post() check in nf_conntrack_hash_check_insert(),\nas well as nf_ct_ext_valid_post() in __nf_conntrack_confirm().\n\nNote that nf_ct_ext_valid_pre() check in __nf_conntrack_confirm() is\nsafe to use NF_CT_STAT_INC(), as it's under local_bh_disable().","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":"netfilter: conntrack: fix using __this_cpu_add in preemptible","id":"CVE-2022-48974","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"denial_of_service","year":"2022"},"n_packages":0,"n_references":2,"next":{"headline":"gpiolib: fix memory leak in gpiochip_setup_dev()","id":"CVE-2022-48975"},"packages":[],"prev":{"headline":"gpio: amd8111: Fix PCI device reference count leak","id":"CVE-2022-48973"},"products":["Linux"],"published":"2024-10-21","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A bug in the Linux kernel netfilter conntrack module causes a kernel panic when handling invalid extension data, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2022-48974/"}
