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-2023-54066 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-2023-54066/ (Markdown: https://insights.sbomify.com/CVE-2023-54066/index.md)","id":"CVE-2023-54066","markdown":"https://insights.sbomify.com/CVE-2023-54066/index.md","name":"CVE-2023-54066","record":{"aliases":["BELL-CVE-2023-54066","DEBIAN-CVE-2023-54066","GHSA-9qq8-wxc9-p23m","UBUNTU-CVE-2023-54066"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A local attacker with physical access can cause a kernel crash in the GL861 DVB-USB driver by sending crafted I2C messages.","user_interaction":"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\nmedia: dvb-usb-v2: gl861: Fix null-ptr-deref in gl861_i2c_master_xfer\n\nIn gl861_i2c_master_xfer, msg is controlled by user.
