# CVE-2019-8922: Memory corruption in n/a > A heap-based buffer overflow in BlueZ allows attackers to execute arbitrary code or cause denial of service via crafted Bluetooth requests. - **Severity:** High 8.8 (`CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`) - **Exploited in the wild:** Not known - **Login needed:** Not needed - **Attackable:** Local or same network only - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 29 Nov 2021 - **Updated:** 15 Apr 2026 - **Also known as:** DEBIAN-CVE-2019-8922, GHSA-r763-g6p5-r323, SUSE-SU-2022:2864-1, SUSE-SU-2022:2900-1, UBUNTU-CVE-2019-8922, USN-5183-1 ## What is CVE-2019-8922? CVE-2019-8922 is a high-severity memory corruption vulnerability in Debian Debian Linux, published on 29 Nov 2021. It can only be exploited from the same machine or local network, with no action from the victim. ### Official description A heap-based buffer overflow was discovered in bluetoothd in BlueZ through 5.48. There isn't any check on whether there is enough space in the destination buffer. The function simply appends all data passed to it. The values of all attributes that are requested are appended to the output buffer. There are no size checks whatsoever, resulting in a simple heap overflow if one can craft a request where the response is large enough to overflow the preallocated buffer. This issue exists in service_attr_req gets called by process_request (in sdpd-request.c), which also allocates the response buffer.

What it is: CVE-2019-8922 is a high-severity memory corruption vulnerability in Debian Debian Linux, published on 29 Nov 2021. It can only be exploited from the same machine or local network, with no action from the victim. Exploitation: There is no known exploitation of CVE-2019-8922 in the wild and no public exploit code. Affected product: Debian Debian Linux. No package-level version data is available, so check the vendor advisory linked from the reference page. Task: 1. 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. 2. 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. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
