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-2026-98730 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-2026-98730/ (Markdown: https://insights.sbomify.com/CVE-2026-98730/index.md)","id":"CVE-2026-98730","markdown":"https://insights.sbomify.com/CVE-2026-98730/index.md","name":"CVE-2026-98730","record":{"aliases":["BELL-CVE-2026-98730","DEBIAN-CVE-2026-98730","GHSA-3249-w698-6rq3","UBUNTU-CVE-2026-98730"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel Bluetooth","requires_auth":"low_privilege","summary":"A local attacker with HCI access can overflow a kernel buffer via oversized Bluetooth packets, potentially leading to code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: btintel_pcie: reject oversized TX packets in send_frame()\n\nbtintel_pcie_send_frame() eventually copies skb-\u003edata into a fixed\nBTINTEL_PCIE_BUFFER_SIZE (4096) DMA buffer via memcpy() in\nbtintel_pcie_prepare_tx(), with a 4-byte PCIe type header prepended.\nA user-space process with HCI_CHANNEL_USER access can inject an\noversized packet and overflow the buffer.\n\nReject packets larger than\nBTINTEL_PCIE_BUFFER_SIZE - BTINTEL_PCIE_HCI_TYPE_LEN on entry.","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: btintel_pcie: reject oversized TX packets in send_frame()","id":"CVE-2026-98730","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"Bluetooth: btintel_pcie: fix plen overflow in btintel_pcie_recv_frame()","id":"CVE-2026-98731"},"packages":[],"prev":{"headline":"x86/mm: Don't apply va_align to hugetlb mappings on AMD F15h","id":"CVE-2026-98729"},"products":["Linux"],"published":"2026-10-18","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"A local attacker with HCI access can overflow a kernel buffer via oversized Bluetooth packets, potentially leading to code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-98730/"}
