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-2026-52922 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-2026-52922/ (Markdown: https://insights.sbomify.com/CVE-2026-52922/index.md)","id":"CVE-2026-52922","markdown":"https://insights.sbomify.com/CVE-2026-52922/index.md","name":"CVE-2026-52922","record":{"aliases":["AZL-90983","BELL-CVE-2026-52922","DEBIAN-CVE-2026-52922","GHSA-jv9r-93q3-fcf8","ROOT-OS-DEBIAN-11-CVE-2026-52922","ROOT-OS-DEBIAN-12-CVE-2026-52922","ROOT-OS-UBUNTU-2204-CVE-2026-52922","ROOT-OS-UBUNTU-2404-CVE-2026-52922","UBUNTU-CVE-2026-52922"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A missing check for allocation failure in the batman-adv module causes a NULL pointer dereference, leading to a kernel crash.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nbatman-adv: dat: handle forward allocation error\n\nbatadv_dat_forward_data() calls pskb_copy_for_clone() to duplicate an skb\nfor each DHT candidate, but does not check the return value before passing\nit to batadv_send_skb_prepare_unicast_4addr().
