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-2026-74304 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-2026-74304/ (Markdown: https://insights.sbomify.com/CVE-2026-74304/index.md)","id":"CVE-2026-74304","markdown":"https://insights.sbomify.com/CVE-2026-74304/index.md","name":"CVE-2026-74304","record":{"aliases":["DEBIAN-CVE-2026-74304","GHSA-3qvf-qw9p-g662","UBUNTU-CVE-2026-74304"],"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 local attacker can cause a kernel crash via a NULL pointer dereference in the Bluetooth QCA driver setup routine.","user_interaction":"not_required","vuln_class":"null_dereference"},"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: hci_qca: fix NULL pointer dereference in qca_setup() for non-serdev device\n\nhu-\u003eserdev is NULL for hci_uart attached via non-serdev paths, but\nqca_setup() unconditionally calls serdev_device_get_drvdata(hu-\u003eserdev)\nand dereferences the result, causing a NULL pointer dereference.\n\nFix by guarding the dereference with a NULL check, consistent with the\nrest of qca_setup().","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: hci_qca: fix NULL pointer dereference in qca_setup() for non-serdev device","id":"CVE-2026-74304","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"bpf: Tighten cgroup storage cookie checks for prog arrays","id":"CVE-2026-74305"},"packages":[],"prev":{"headline":"Bluetooth: hci_qca: fix NULL pointer dereference in qca_dmp_hdr() for non-serdev device","id":"CVE-2026-74303"},"products":["Linux"],"published":"2026-08-15","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":"2026-09-25","vendors":["Linux"]},"summary":"A local attacker can cause a kernel crash via a NULL pointer dereference in the Bluetooth QCA driver setup routine.","url":"https://insights.sbomify.com/CVE-2026-74304/"}
