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-2026-21736 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-2026-21736/ (Markdown: https://insights.sbomify.com/CVE-2026-21736/index.md)","id":"CVE-2026-21736","markdown":"https://insights.sbomify.com/CVE-2026-21736/index.md","name":"CVE-2026-21736","record":{"aliases":["A-382331631","ASB-A-382331631","GHSA-vjrg-fwqx-82jx"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Android GPU driver","requires_auth":"low_privilege","summary":"A non-privileged user can gain write access to read-only memory via improper GPU system calls, requiring write attribute support to be enabled.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"imaginationtech","cpe":[{"product":"ddk","vendor":"imaginationtech"}],"cvss":{"score":4.4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-280","name":"Improper Handling of Insufficient Permissions or Privileges"}],"description":"Software installed and run as a non-privileged user may conduct improper GPU system calls to gain write permission to read-only wrapped user-mode memory.\n\nThis is caused by improper handling of the memory protections for the user-mode wrapped memory resource.","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 - Insufficient permission check in PhysmemWrapExtMem() when write attribute support enabled","id":"CVE-2026-21736","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Open redirect in FortiNAC-F","id":"CVE-2026-21741"},"packages":[],"prev":{"headline":"GPU DDK - libusc OOB write at TreeRemove during WebGPU shader compilation","id":"CVE-2026-21734"},"products":["Graphics DDK"],"published":"2026-03-09","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":"partial"},"state":"PUBLISHED","updated":"2026-03-09","vendors":["Imagination Technologies"]},"summary":"A non-privileged user can gain write access to read-only memory via improper GPU system calls, requiring write attribute support to be enabled.","url":"https://insights.sbomify.com/CVE-2026-21736/"}
