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-2026-7477 in the wild and no public exploit code.\n\nAffected product: Arm 5th Gen GPU Architecture 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-2026-7477/ (Markdown: https://insights.sbomify.com/CVE-2026-7477/index.md)","id":"CVE-2026-7477","markdown":"https://insights.sbomify.com/CVE-2026-7477/index.md","name":"CVE-2026-7477","record":{"aliases":["A-525773732","ASB-A-525773732","GHSA-77xw-jh9c-7m36"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"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 Arm Mali GPU drivers on Android to access freed memory, potentially leading to code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Arm","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Use After Free vulnerability in Arm Ltd Bifrost GPU Kernel Driver, Arm Ltd Valhall GPU Kernel Driver, Arm Ltd Arm 5th Gen GPU Architecture Kernel Driver allows a local non-privileged user process to perform valid GPU memory processing operations to access already freed memory.\n\nThis issue affects Bifrost GPU Kernel Driver: from r44p0 through r49p4, from r50p0 through r51p0, from r54p1 through r54p2; Valhall GPU Kernel Driver: from r44p0 through r49p5, from r50p0 through r54p3; Arm 5th Gen GPU Architecture Kernel Driver: from r44p0 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":true,"headline":"Mali GPU Kernel Driver allows access to already freed memory","id":"CVE-2026-7477","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":"Privilege escalation in ASUS System Control Interface","id":"CVE-2026-7480"},"packages":[],"prev":{"headline":"Mali GPU Kernel Driver allows access to already freed memory","id":"CVE-2026-7476"},"products":["Arm 5th Gen GPU Architecture Kernel Driver","Bifrost GPU Kernel Driver","Valhall GPU Kernel 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":"total"},"state":"PUBLISHED","updated":"2026-09-10","vendors":["Arm Ltd"]},"summary":"A local attacker can exploit a use-after-free flaw in Arm Mali GPU drivers on Android to access freed memory, potentially leading to code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-7477/"}
