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-2026-89808 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-2026-89808/ (Markdown: https://insights.sbomify.com/CVE-2026-89808/index.md)","id":"CVE-2026-89808","markdown":"https://insights.sbomify.com/CVE-2026-89808/index.md","name":"CVE-2026-89808","record":{"aliases":["AZL-101415","BELL-CVE-2026-89808","DEBIAN-CVE-2026-89808","GHSA-r66w-v4mr-3pxg","UBUNTU-CVE-2026-89808"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A flaw in the Linux kernel's AMD GPU driver allows a local attacker to cause a denial of service by triggering an uninitialized variable usage during memory migration.","user_interaction":"not_required","vuln_class":"null_dereference"},"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\ndrm/amdkfd: Fix the case that vm range is hole at svm_migrate_copy_to_vram\n\nWhen migration vm range is hole at cpu side(MIGRATE_PFN_MIGRATE set +\nMIGRATE_PFN_VALID unset) driver still allocates device pages.
