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-2026-64520 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-2026-64520/ (Markdown: https://insights.sbomify.com/CVE-2026-64520/index.md)","id":"CVE-2026-64520","markdown":"https://insights.sbomify.com/CVE-2026-64520/index.md","name":"CVE-2026-64520","record":{"aliases":["BELL-CVE-2026-64520","DEBIAN-CVE-2026-64520","GHSA-p6rc-3j29-m628","ROOT-OS-DEBIAN-13-CVE-2026-64520","ROOT-OS-UBUNTU-2204-CVE-2026-64520","UBUNTU-CVE-2026-64520"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A missing bounds check in the Linux kernel's ARM FFA driver allows out-of-bounds writes, potentially leading to code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/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\nfirmware: arm_ffa: Bound PARTITION_INFO_GET_REGS copies\n\nThe register-based PARTITION_INFO_GET path trusted the firmware-provided\nindices when copying partition descriptors into the caller buffer.\nReject inconsistent counts or index progressions so the copy loop cannot\nwrite past the allocated array.\n\n(fixed cur_idx when exactly one descriptor in the first fragment)","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":"firmware: arm_ffa: Bound PARTITION_INFO_GET_REGS copies","id":"CVE-2026-64520","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"pinctrl: meson: amlogic-a4: fix deadlock issue","id":"CVE-2026-64521"},"packages":[],"prev":{"headline":"NFSD: Fix infinite loop in layout state revocation","id":"CVE-2026-64519"},"products":["Linux"],"published":"2026-07-25","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"A missing bounds check in the Linux kernel's ARM FFA driver allows out-of-bounds writes, potentially leading to code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-64520/"}
