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-2023-4272 in the wild and no public exploit code.\n\nAffected product: Arm Valhall Gpu Kernel Driver. 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-2023-4272/ (Markdown: https://insights.sbomify.com/CVE-2023-4272/index.md)","id":"CVE-2023-4272","markdown":"https://insights.sbomify.com/CVE-2023-4272/index.md","name":"CVE-2023-4272","record":{"aliases":["A-296910715","ASB-A-296910715","GHSA-gh94-rfj3-873r"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Mali GPU Kernel Driver","requires_auth":"low_privilege","summary":"A local attacker can exploit Mali GPU kernel drivers to read sensitive data from previously freed memory, requiring OS-level patches.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Arm","cpe":[{"product":"bifrost_gpu_kernel_driver","vendor":"arm"},{"product":"mali_gpu_kernel_driver","vendor":"arm"},{"product":"midgard_gpu_kernel_driver","vendor":"arm"},{"product":"valhall_gpu_kernel_driver","vendor":"arm"}],"cvss":{"score":5.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"},{"id":"CWE-1251","name":"Mirrored Regions with Different Values"}],"description":"A local non-privileged user can make GPU processing operations that expose sensitive data from previously freed memory.","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":"Mali GPU Kernel Driver exposes sensitive data from freed memory","id":"CVE-2023-4272","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"arm:valhall_gpu_kernel_driver","products":["arm:valhall_gpu_kernel_driver"],"type":"information_disclosure","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Kernel: exfat: stack overflow in exfat_get_uniname_from_ext_entry","id":"CVE-2023-4273"},"packages":[],"prev":{"headline":"Photospace Responsive \u003c= 2.1.1 - Authenticated (Administrator+) Stored Cross-Site Scripting","id":"CVE-2023-4271"},"products":["Arm 5th Gen GPU Architecture Kernel  Driver","Bifrost GPU Kernel Driver","Midgard GPU Kernel Driver","Valhall GPU Kernel Driver"],"published":"2023-11-07","related":[{"cvss_score":8.8,"headline":"Arm Mali GPU Kernel Driver Use-After-Free","id":"CVE-2022-38181","kev_date_added":"2023-03-30","published":"2022-10-25"},{"cvss_score":8.8,"headline":"Arm Mali GPU Kernel Driver Use-After-Free","id":"CVE-2021-29256","kev_date_added":"2023-07-07","published":"2021-05-24"},{"cvss_score":8.8,"headline":"Arm Mali Graphics Processing Unit (GPU) Use-After-Free","id":"CVE-2021-28663","kev_date_added":"2021-11-03","published":"2021-05-10"},{"cvss_score":8.8,"headline":"Arm Mali Graphics Processing Unit (GPU) Unspecified","id":"CVE-2021-28664","kev_date_added":"2021-11-03","published":"2021-05-10"},{"cvss_score":7.8,"headline":"Arm Mali GPU Kernel Driver Unspecified","id":"CVE-2022-22706","kev_date_added":"2023-03-30","published":"2022-03-03"},{"cvss_score":7.4,"headline":"Arm Mali GPU Kernel Driver Use-After-Free","id":"CVE-2024-4610","kev_date_added":"2024-06-12","published":"2024-06-07"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2022-28348","kev_date_added":null,"published":"2022-05-19"}],"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-09-04","vendors":["Arm Ltd"]},"summary":"A local attacker can exploit Mali GPU kernel drivers to read sensitive data from previously freed memory, requiring OS-level patches.","url":"https://insights.sbomify.com/CVE-2023-4272/"}
