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-2026-72093 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2026-72093/ (Markdown: https://insights.sbomify.com/CVE-2026-72093/index.md)","id":"CVE-2026-72093","markdown":"https://insights.sbomify.com/CVE-2026-72093/index.md","name":"CVE-2026-72093","record":{"aliases":["BELL-CVE-2026-72093","DEBIAN-CVE-2026-72093","GHSA-6xqj-5m3m-7w3w","UBUNTU-CVE-2026-72093"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A use-after-free in the AMD XDNA accelerator driver allows attackers to execute arbitrary code or escalate privileges via double-free logic.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\naccel/amdxdna: Fix use-after-free in amdxdna_gem_dmabuf_mmap()\n\nWhen vm_insert_pages() fails, the error path calls vma-\u003evm_ops-\u003eclose(vma)\nwhich internally calls drm_gem_vm_close() → drm_gem_object_put(),\nreleasing the GEM object reference acquired at the start of the function.\nHowever, the close_vma label then falls through to put_obj, which calls\ndrm_gem_object_put() a second time on the same object.\n\nIf the first put releases the last reference, the object is freed and the\nsecond put accesses freed memory, causing a use-after-free.\n\nFix by returning directly from close_vma instead of falling through to\nput_obj, since the close handler already performs all necessary cleanup\nincluding the object put.","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":"accel/amdxdna: Fix use-after-free in amdxdna_gem_dmabuf_mmap()","id":"CVE-2026-72093","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"dma-buf: dma-fence: Fix potential NULL pointer dereference","id":"CVE-2026-72094"},"packages":[],"prev":{"headline":"accel/amdxdna: reject command submission on devices without a submit op","id":"CVE-2026-72092"},"products":["Linux"],"published":"2026-08-15","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-17","vendors":["Linux"]},"summary":"A use-after-free in the AMD XDNA accelerator driver allows attackers to execute arbitrary code or escalate privileges via double-free logic.","url":"https://insights.sbomify.com/CVE-2026-72093/"}
