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-2026-72311 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-2026-72311/ (Markdown: https://insights.sbomify.com/CVE-2026-72311/index.md)","id":"CVE-2026-72311","markdown":"https://insights.sbomify.com/CVE-2026-72311/index.md","name":"CVE-2026-72311","record":{"aliases":["DEBIAN-CVE-2026-72311","GHSA-69mf-3x6r-xpp9","UBUNTU-CVE-2026-72311"],"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":"A memory leak in the Linux kernel's Xe GPU driver allows local attackers to exhaust system memory via repeated failed ioctl calls, causing denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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/xe: free madvise VMA array on L2 flush failure\n\nxe_vm_madvise_ioctl() allocates madvise_range.vmas in get_vmas().\nAfter get_vmas() succeeds with at least one VMA, error paths must go\nthrough free_vmas so the array is released before the madvise details are\ndestroyed.\n\nThe L2 flush validation path added for PAT madvise rejects some\nSVM/userptr ranges after get_vmas() has succeeded, but jumps directly to\nmadv_fini.
