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-2026-53147 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2026-53147/ (Markdown: https://insights.sbomify.com/CVE-2026-53147/index.md)","id":"CVE-2026-53147","markdown":"https://insights.sbomify.com/CVE-2026-53147/index.md","name":"CVE-2026-53147","record":{"aliases":["AZL-90585","BELL-CVE-2026-53147","DEBIAN-CVE-2026-53147","GHSA-vrfr-cw9w-gwrx","ROOT-OS-DEBIAN-11-CVE-2026-53147","ROOT-OS-DEBIAN-12-CVE-2026-53147","ROOT-OS-UBUNTU-2204-CVE-2026-53147","ROOT-OS-UBUNTU-2404-CVE-2026-53147","UBUNTU-CVE-2026-53147"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A malicious Thunderbolt peer can trigger out-of-bounds reads in the Linux kernel by sending undersized XDomain packets, potentially causing information disclosure or crashes.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nthunderbolt: Validate XDomain request packet size before type cast\n\ntb_xdp_handle_request() casts the received packet buffer to\nprotocol-specific structs without verifying that the allocation\nis large enough for the target type.
