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-2026-97977 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-2026-97977/ (Markdown: https://insights.sbomify.com/CVE-2026-97977/index.md)","id":"CVE-2026-97977","markdown":"https://insights.sbomify.com/CVE-2026-97977/index.md","name":"CVE-2026-97977","record":{"aliases":["AZL-104853","BELL-CVE-2026-97977","DEBIAN-CVE-2026-97977","GHSA-mvpx-42x3-8643","UBUNTU-CVE-2026-97977"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel Bluetooth","requires_auth":"none","summary":"A use-after-free in the Linux kernel Bluetooth USB driver allows attackers with physical or local access to execute arbitrary code or crash the system.","user_interaction":"not_required","vuln_class":"use_after_free"},"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: btusb: Fix UAF of btusb_data by rx_work\n\nbtusb_close() and btusb_flush() cancel data-\u003erx_work with the\nasynchronous cancel_delayed_work(), so if btusb_rx_work() is already\nrunning on another CPU it keeps running after the cancel returns.\n\nbtusb_disconnect() calls hci_unregister_dev(), which invokes\nbtusb_close(), and then frees the btusb_data.
