An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-23048 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2026-23048/ (Markdown: https://insights.sbomify.com/CVE-2026-23048/index.md)","id":"CVE-2026-23048","markdown":"https://insights.sbomify.com/CVE-2026-23048/index.md","name":"CVE-2026-23048","record":{"aliases":["BELL-CVE-2026-23048","DEBIAN-CVE-2026-23048","GHSA-h5xw-xh97-3j7m","UBUNTU-CVE-2026-23048"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A missing skb_orphan call in the Linux kernel UDP receive path can trigger a warning and potential instability, requiring a kernel patch.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nudp: call skb_orphan() before skb_attempt_defer_free()\n\nStandard UDP receive path does not use skb-\u003edestructor.\n\nBut skmsg layer does use it, since it calls skb_set_owner_sk_safe()\nfrom udp_read_skb().\n\nThis then triggers this warning in skb_attempt_defer_free():\n\n    DEBUG_NET_WARN_ON_ONCE(skb-\u003edestructor);\n\nWe must call skb_orphan() to fix this issue.","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":"udp: call skb_orphan() before skb_attempt_defer_free()","id":"CVE-2026-23048","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"drm/panel-simple: fix connector type for DataImage SCF0700C48GGU18 panel","id":"CVE-2026-23049"},"packages":[],"prev":{"headline":"libceph: make calc_target() set t-\u003epaused, not just clear it","id":"CVE-2026-23047"},"products":["Linux"],"published":"2026-02-04","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A missing skb_orphan call in the Linux kernel UDP receive path can trigger a warning and potential instability, requiring a kernel patch.","url":"https://insights.sbomify.com/CVE-2026-23048/"}
