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-2025-68808 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-2025-68808/ (Markdown: https://insights.sbomify.com/CVE-2025-68808/index.md)","id":"CVE-2025-68808","markdown":"https://insights.sbomify.com/CVE-2025-68808/index.md","name":"CVE-2025-68808","record":{"aliases":["BELL-CVE-2025-68808","DEBIAN-CVE-2025-68808","GHSA-9hm8-83j2-jcqx","ROOT-OS-DEBIAN-11-CVE-2025-68808","ROOT-OS-DEBIAN-12-CVE-2025-68808","ROOT-OS-DEBIAN-13-CVE-2025-68808","ROOT-OS-UBUNTU-2204-CVE-2025-68808","ROOT-OS-UBUNTU-2404-CVE-2025-68808","UBUNTU-CVE-2025-68808"],"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 media driver","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel vidtv driver allows attackers to cause denial of service or execute arbitrary code via improper pointer initialization.","user_interaction":"not_required","vuln_class":"use_after_free"},"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\nmedia: vidtv: initialize local pointers upon transfer of memory ownership\n\nvidtv_channel_si_init() creates a temporary list (program, service, event)\nand ownership of the memory itself is transferred to the PAT/SDT/EIT\ntables through vidtv_psi_pat_program_assign(),\nvidtv_psi_sdt_service_assign(), vidtv_psi_eit_event_assign().\n\nThe problem here is that the local pointer where the memory ownership\ntransfer was completed is not initialized to NULL.
