An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-31405 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-2026-31405/ (Markdown: https://insights.sbomify.com/CVE-2026-31405/index.md)","id":"CVE-2026-31405","markdown":"https://insights.sbomify.com/CVE-2026-31405/index.md","name":"CVE-2026-31405","record":{"aliases":["BELL-CVE-2026-31405","DEBIAN-CVE-2026-31405","GHSA-qqxp-95qg-gqxr","ROOT-OS-DEBIAN-11-CVE-2026-31405","ROOT-OS-DEBIAN-12-CVE-2026-31405","ROOT-OS-DEBIAN-13-CVE-2026-31405","ROOT-OS-UBUNTU-2204-CVE-2026-31405","ROOT-OS-UBUNTU-2404-CVE-2026-31405","UBUNTU-CVE-2026-31405"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"An out-of-bounds read in the Linux kernel DVB network driver allows attackers to trigger memory corruption or execute arbitrary code via crafted network packets.","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":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/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\nmedia: dvb-net: fix OOB access in ULE extension header tables\n\nThe ule_mandatory_ext_handlers[] and ule_optional_ext_handlers[] tables\nin handle_one_ule_extension() are declared with 255 elements (valid\nindices 0-254), but the index htype is derived from network-controlled\ndata as (ule_sndu_type \u0026 0x00FF), giving a range of 0-255.
