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-2026-7639 in the wild and no public exploit code.\n\nAffected product: Imagination Technologies Graphics DDK. 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-2026-7639/ (Markdown: https://insights.sbomify.com/CVE-2026-7639/index.md)","id":"CVE-2026-7639","markdown":"https://insights.sbomify.com/CVE-2026-7639/index.md","name":"CVE-2026-7639","record":{"aliases":["A-505486043","ASB-A-505486043","GHSA-q4g7-pm99-9f7g"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Android GPU driver","requires_auth":"low_privilege","summary":"A malicious app can trigger a use-after-free in the GPU driver to read unauthorized physical memory and potentially escalate privileges.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"imaginationtech","cpe":[{"product":"ddk","vendor":"imaginationtech"}],"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-459","name":"Incomplete Cleanup"}],"description":"Software installed and run as a non-privileged user may conduct a sequence of improper GPU system calls causing use after free, which helps in facilitating unprivileged memory access from a shader code.\n\nTriggering failure path in the MMU mapping logic by a malicious code could lead to incomplete cleanup of an internal driver state, allowing for future unauthorized access to the contents of the physical 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":"GPU DDK - Page UAF read in PMMETA_PROTECT heap memory","id":"CVE-2026-7639","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":"WP Customer Area \u003c= 8.3.5 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'type' Shortcode Attribute","id":"CVE-2026-7640"},"packages":[],"prev":{"headline":"Missing authorization in App Builder – Create Native Android \u0026 iOS Apps On The Flight","id":"CVE-2026-7638"},"products":["Graphics DDK"],"published":"2026-07-10","related":[{"cvss_score":9.8,"headline":"GPU DDK - Integer overflow in _PMRLogicalOffsetToPhysicalOffset","id":"CVE-2026-16280","kev_date_added":null,"published":"2026-07-24"},{"cvss_score":9.8,"headline":"GPU DDK - libusc UAF via WebGPU shaders at MergeConsecutiveBarriersBP","id":"CVE-2025-13952","kev_date_added":null,"published":"2026-01-24"},{"cvss_score":9.6,"headline":"GPU DDK - libusc OOB write at ConvertSwitchToArrayLookupBP during WebGPU shader compilation","id":"CVE-2026-21732","kev_date_added":null,"published":"2026-03-20"},{"cvss_score":9.1,"headline":"GPU DDK - GPU Register value contents leaked from secure workloads to non-secure world","id":"CVE-2025-25176","kev_date_added":null,"published":"2026-01-13"},{"cvss_score":8.8,"headline":"GPU DDK - Reservation::psMappedPMR can change while used by a freelist -\u003e UAF","id":"CVE-2025-58411","kev_date_added":null,"published":"2026-01-13"},{"cvss_score":8.2,"headline":"GPU DDK - rgxfw_hwperf_get_packet_buffer OOB write","id":"CVE-2025-0467","kev_date_added":null,"published":"2025-04-18"},{"cvss_score":8.1,"headline":"GPU DDK - UAF read of GLES3Context::psDrawParams and GLES3Context::psMode and UAF read/write of RMJob::apsCCBs","id":"CVE-2026-22165","kev_date_added":null,"published":"2026-05-01"}],"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":"2026-07-13","vendors":["Imagination Technologies"]},"summary":"A malicious app can trigger a use-after-free in the GPU driver to read unauthorized physical memory and potentially escalate privileges.","url":"https://insights.sbomify.com/CVE-2026-7639/"}
