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-2026-74258 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-2026-74258/ (Markdown: https://insights.sbomify.com/CVE-2026-74258/index.md)","id":"CVE-2026-74258","markdown":"https://insights.sbomify.com/CVE-2026-74258/index.md","name":"CVE-2026-74258","record":{"aliases":["AZL-96552","BELL-CVE-2026-74258","DEBIAN-CVE-2026-74258","GHSA-pwvf-7f5w-2qr5","UBUNTU-CVE-2026-74258"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel BPF","requires_auth":"low_privilege","summary":"Missing access_ok check in Linux kernel BPF uprobe_multi allows unauthorized user-space memory access, potentially leading to privilege escalation or data leaks.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Guard __get_user acesss with access_ok for uprobe_multi data\n\nAs reported by sashiko [1] we need to use access_ok to check the user\nspace data bounds before we use __get-user to get it.\n\n[1] https://lore.kernel.org/bpf/20260610145235.CB1441F00893@smtp.kernel.org/","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":"bpf: Guard __get_user acesss with access_ok for uprobe_multi data","id":"CVE-2026-74258","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.","id":"CVE-2026-74259"},"packages":[],"prev":{"headline":"sockmap: Fix use-after-free in udp_bpf_recvmsg()","id":"CVE-2026-74257"},"products":["Linux"],"published":"2026-08-15","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-16","vendors":["Linux"]},"summary":"Missing access_ok check in Linux kernel BPF uprobe_multi allows unauthorized user-space memory access, potentially leading to privilege escalation or data leaks.","url":"https://insights.sbomify.com/CVE-2026-74258/"}
