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-2026-74303 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-2026-74303/ (Markdown: https://insights.sbomify.com/CVE-2026-74303/index.md)","id":"CVE-2026-74303","markdown":"https://insights.sbomify.com/CVE-2026-74303/index.md","name":"CVE-2026-74303","record":{"aliases":["BELL-CVE-2026-74303","DEBIAN-CVE-2026-74303","GHSA-c62v-fhpj-c23c","UBUNTU-CVE-2026-74303"],"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 NULL pointer dereference in the Linux kernel Bluetooth driver allows local attackers to cause a system crash.","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_dmp_hdr() for non-serdev device\n\nhu-\u003eserdev is NULL for hci_uart attached via non-serdev paths, but\nqca_dmp_hdr() unconditionally dereferences hu-\u003eserdev-\u003edev.driver-\u003ename,\ncausing a NULL pointer dereference.\n\nFix by guarding the dereference with a NULL check and falling back to\n\"hci_ldisc_qca\" for the non-serdev case.","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_dmp_hdr() for non-serdev device","id":"CVE-2026-74303","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"Bluetooth: hci_qca: fix NULL pointer dereference in qca_setup() for non-serdev device","id":"CVE-2026-74304"},"packages":[],"prev":{"headline":"Bluetooth: hci_core: Fix UAF in hci_unregister_dev()","id":"CVE-2026-74302"},"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":"2026-08-17","vendors":["Linux"]},"summary":"A NULL pointer dereference in the Linux kernel Bluetooth driver allows local attackers to cause a system crash.","url":"https://insights.sbomify.com/CVE-2026-74303/"}
