It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-19774 in the wild and no public exploit code.\n\nAffected product: BlueZ. 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-2026-19774/ (Markdown: https://insights.sbomify.com/CVE-2026-19774/index.md)","id":"CVE-2026-19774","markdown":"https://insights.sbomify.com/CVE-2026-19774/index.md","name":"CVE-2026-19774","record":{"aliases":["AZL-103122","DEBIAN-CVE-2026-19774","GHSA-53cx-rp5p-x795","ROOT-OS-DEBIAN-12-CVE-2026-19774","ROOT-OS-DEBIAN-13-CVE-2026-19774","UBUNTU-CVE-2026-19774","USN-8908-2"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"BlueZ Bluetooth stack","requires_auth":"none","summary":"Network-adjacent attackers can execute arbitrary code with root privileges via a stack-based buffer overflow in BlueZ A2DP handling after pairing.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:A/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"BlueZ A2DP Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of BlueZ. An attacker must first obtain the ability to pair a malicious Bluetooth device with the target system in order to exploit this vulnerability.\n\nThe specific flaw exists within the handling of the stream endpoints. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer.
