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-2026-72045 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-2026-72045/ (Markdown: https://insights.sbomify.com/CVE-2026-72045/index.md)","id":"CVE-2026-72045","markdown":"https://insights.sbomify.com/CVE-2026-72045/index.md","name":"CVE-2026-72045","record":{"aliases":["BELL-CVE-2026-72045","DEBIAN-CVE-2026-72045","GHSA-5g45-v3m4-8hc5","UBUNTU-CVE-2026-72045"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A missing authorization check in the Linux kernel octeontx2-af driver allows a virtual function to read physical memory addresses from other functions, potentially leading to privilege escalation.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nocteontx2-af: cn10k: restrict VF LMTLINE sharing to its own PF\n\nrvu_mbox_handler_lmtst_tbl_setup() uses req-\u003ebase_pcifunc as a direct\nindex into the LMT map table to read another function's LMTLINE\nphysical base address and copy it into the caller's own LMT map table\nentry.
