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-2026-80888 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-2026-80888/ (Markdown: https://insights.sbomify.com/CVE-2026-80888/index.md)","id":"CVE-2026-80888","markdown":"https://insights.sbomify.com/CVE-2026-80888/index.md","name":"CVE-2026-80888","record":{"aliases":["AZL-99684","BELL-CVE-2026-80888","DEBIAN-CVE-2026-80888","GHSA-3r89-cxvf-8cx5","UBUNTU-CVE-2026-80888"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"An unprivileged local user can leak DMA buffer references in the vmwgfx driver, causing memory exhaustion and denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/vmwgfx: drop dma_buf reference on foreign-fd prime import\n\nttm_prime_fd_to_handle() returns -ENOSYS when the imported fd's\ndma_buf-\u003eops do not match the ttm_object_device's ops, but does so\nwithout releasing the reference acquired by dma_buf_get().
