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-2025-40282 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-2025-40282/ (Markdown: https://insights.sbomify.com/CVE-2025-40282/index.md)","id":"CVE-2025-40282","markdown":"https://insights.sbomify.com/CVE-2025-40282/index.md","name":"CVE-2025-40282","record":{"aliases":["BELL-CVE-2025-40282","DEBIAN-CVE-2025-40282","GHSA-5r7j-r8w6-f8xc","ROOT-OS-DEBIAN-12-CVE-2025-40282","ROOT-OS-DEBIAN-13-CVE-2025-40282","ROOT-OS-UBUNTU-2204-CVE-2025-40282","ROOT-OS-UBUNTU-2404-CVE-2025-40282","UBUNTU-CVE-2025-40282"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel Bluetooth","requires_auth":"none","summary":"A missing header reset in the Linux kernel Bluetooth 6lowpan module causes a kernel crash when receiving raw IPv6 packets.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/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\nBluetooth: 6lowpan: reset link-local header on ipv6 recv path\n\nBluetooth 6lowpan.c netdev has header_ops, so it must set link-local\nheader for RX skb, otherwise things crash, eg. with AF_PACKET SOCK_RAW\n\nAdd missing skb_reset_mac_header() for uncompressed ipv6 RX path.\n\nFor the compressed one, it is done in lowpan_header_decompress().\n\nLog: (BlueZ 6lowpan-tester Client Recv Raw - Success)\n------\nkernel BUG at net/core/skbuff.c:212!\nCall Trace:\n\u003cIRQ\u003e\n...\npacket_rcv (net/packet/af_packet.c:2152)\n...\n\u003cTASK\u003e\n__local_bh_enable_ip (kernel/softirq.c:407)\nnetif_rx (net/core/dev.c:5648)\nchan_recv_cb (net/bluetooth/6lowpan.c:294 net/bluetooth/6lowpan.c:359)\n------","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Bluetooth: 6lowpan: reset link-local header on ipv6 recv path","id":"CVE-2025-40282","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2025"},"n_packages":0,"n_references":8,"next":{"headline":"Bluetooth: btusb: reorder cleanup in btusb_disconnect to avoid UAF","id":"CVE-2025-40283"},"packages":[],"prev":{"headline":"sctp: prevent possible shift-out-of-bounds in sctp_transport_update_rto","id":"CVE-2025-40281"},"products":["Linux"],"published":"2025-12-06","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"A missing header reset in the Linux kernel Bluetooth 6lowpan module causes a kernel crash when receiving raw IPv6 packets.","url":"https://insights.sbomify.com/CVE-2025-40282/"}
