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-2025-68819 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-2025-68819/ (Markdown: https://insights.sbomify.com/CVE-2025-68819/index.md)","id":"CVE-2025-68819","markdown":"https://insights.sbomify.com/CVE-2025-68819/index.md","name":"CVE-2025-68819","record":{"aliases":["BELL-CVE-2025-68819","DEBIAN-CVE-2025-68819","GHSA-7rq6-3vvj-vpcc","ROOT-OS-DEBIAN-11-CVE-2025-68819","ROOT-OS-DEBIAN-12-CVE-2025-68819","ROOT-OS-DEBIAN-13-CVE-2025-68819","ROOT-OS-UBUNTU-2204-CVE-2025-68819","ROOT-OS-UBUNTU-2404-CVE-2025-68819","UBUNTU-CVE-2025-68819"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A missing bounds check in the dtv5100 USB driver allows out-of-bounds memory access, potentially leading to code execution or system crashes.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: dvb-usb: dtv5100: fix out-of-bounds in dtv5100_i2c_msg()\n\nrlen value is a user-controlled value, but dtv5100_i2c_msg() does not\ncheck the size of the rlen value.
