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-2026-11891 in the wild and no public exploit code.\n\nAffected product: Arm 5th Gen GPU Architecture Userspace 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-2026-11891/ (Markdown: https://insights.sbomify.com/CVE-2026-11891/index.md)","id":"CVE-2026-11891","markdown":"https://insights.sbomify.com/CVE-2026-11891/index.md","name":"CVE-2026-11891","record":{"aliases":["GHSA-v44f-6g2r-3454"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["data_read","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Mali GPU driver","requires_auth":"none","summary":"A use-after-free flaw in Arm Mali GPU drivers allows non-privileged users to access freed memory via WebGL or WebGPU, potentially leading to information disclosure or code execution.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Arm","cpe":[],"cvss":{"score":5.1,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Use After Free vulnerability in Arm Ltd Valhall GPU Userspace Driver, Arm Ltd Arm 5th Gen GPU Architecture Userspace Driver allows a non-privileged user process to perform valid GPU processing operations, including via WebGL or WebGPU, to access already freed memory.\n\nThis issue affects Valhall GPU Userspace Driver: from r46p0 through r49p5, from r50p0 through r54p3, r55p0; Arm 5th Gen GPU Architecture Userspace Driver: from r46p0 through r49p5, from r50p0 through r54p3, r55p0.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Mali GPU Userspace Driver allows access to already freed memory","id":"CVE-2026-11891","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Double free / use-after-free in Bouffalo Lab HCI driver send() error paths (hci_bflb)","id":"CVE-2026-11893"},"packages":[],"prev":{"headline":"Missing authorization in Devolutions Server","id":"CVE-2026-11890"},"products":["Arm 5th Gen GPU Architecture Userspace Driver","Valhall GPU Userspace Driver"],"published":"2026-09-08","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-09-10","vendors":["Arm Ltd"]},"summary":"A use-after-free flaw in Arm Mali GPU drivers allows non-privileged users to access freed memory via WebGL or WebGPU, potentially leading to information disclosure or code execution.","url":"https://insights.sbomify.com/CVE-2026-11891/"}
