It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2023-4211 in the wild since at least 3 Oct 2023.\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-2023-4211/ (Markdown: https://insights.sbomify.com/CVE-2023-4211/index.md)","id":"CVE-2023-4211","markdown":"https://insights.sbomify.com/CVE-2023-4211/index.md","name":"CVE-2023-4211","record":{"aliases":["A-294605494","ASB-A-294605494","GHSA-7537-p54v-mh3v","PUB-A-294605494"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Android GPU driver","requires_auth":"low_privilege","summary":"A local attacker can exploit a use-after-free flaw in the Mali GPU kernel driver to access freed memory, potentially leading to privilege escalation or code execution.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Arm","cpe":[{"product":"5th_gen_gpu_architecture_kernel_driver","vendor":"arm"},{"product":"bifrost_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-416","name":"Use After Free"}],"description":"A local non-privileged user can make improper GPU memory processing operations  to gain access to already freed memory.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"exploited"},"has_fix":true,"headline":"Arm Mali GPU Kernel Driver Use-After-Free","id":"CVE-2023-4211","indexable":true,"kev":{"dateAdded":"2023-10-03","dueDate":"2023-10-24","knownRansomwareCampaignUse":"Unknown","product":"Mali GPU Kernel Driver","requiredAction":"Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.","vendorProject":"Arm","vulnerabilityName":"Arm Mali GPU Kernel Driver Use-After-Free Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"arm:valhall_gpu_kernel_driver","products":["arm:valhall_gpu_kernel_driver"],"type":"use_after_free","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Trane Thermostats Injection","id":"CVE-2023-4212"},"packages":[],"prev":{"headline":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.","id":"CVE-2023-4210"},"products":["Arm 5th Gen GPU Architecture Kernel  Driver","Bifrost GPU Kernel Driver","Midgard GPU Kernel Driver","Valhall GPU Kernel Driver"],"published":"2023-10-01","related":[{"cvss_score":3.3,"headline":"Arm Mali GPU Kernel Driver Information Disclosure","id":"CVE-2023-26083","kev_date_added":"2023-04-07","published":"2023-04-06"},{"cvss_score":8.4,"headline":"Mali GPU Kernel Driver allows improper GPU memory processing operations","id":"CVE-2023-6143","kev_date_added":null,"published":"2024-03-04"},{"cvss_score":7.8,"headline":"Mali GPU Kernel Driver allows improper GPU memory processing operations","id":"CVE-2025-0073","kev_date_added":null,"published":"2025-06-02"},{"cvss_score":7.8,"headline":"Mali GPU Kernel Driver allows access to already freed memory","id":"CVE-2025-0819","kev_date_added":null,"published":"2025-06-02"},{"cvss_score":7.8,"headline":"Mali GPU Kernel Driver allows improper GPU memory processing operations","id":"CVE-2025-0072","kev_date_added":null,"published":"2025-05-02"},{"cvss_score":7.8,"headline":"Mali GPU Kernel Driver allows access to already freed memory","id":"CVE-2025-0427","kev_date_added":null,"published":"2025-05-02"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["Arm Ltd"]},"summary":"A local attacker can exploit a use-after-free flaw in the Mali GPU kernel driver to access freed memory, potentially leading to privilege escalation or code execution.","url":"https://insights.sbomify.com/CVE-2023-4211/"}
