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-2023-54263 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-2023-54263/ (Markdown: https://insights.sbomify.com/CVE-2023-54263/index.md)","id":"CVE-2023-54263","markdown":"https://insights.sbomify.com/CVE-2023-54263/index.md","name":"CVE-2023-54263","record":{"aliases":["BELL-CVE-2023-54263","DEBIAN-CVE-2023-54263","GHSA-7v8c-h9vh-3q7f","ROOT-OS-DEBIAN-11-CVE-2023-54263","ROOT-OS-DEBIAN-12-CVE-2023-54263","ROOT-OS-UBUNTU-2204-CVE-2023-54263","UBUNTU-CVE-2023-54263"],"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 missing lock initialization in the nouveau driver causes a kernel OOPS on systems with ANX9805 DP encoders, leading to denial of service.","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\ndrm/nouveau/kms/nv50-: init hpd_irq_lock for PIOR DP\n\nFixes OOPS on boards with ANX9805 DP encoders.","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":"drm/nouveau/kms/nv50-: init hpd_irq_lock for PIOR DP","id":"CVE-2023-54263","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"fs/sysv: Null check to prevent null-ptr-deref bug","id":"CVE-2023-54264"},"packages":[],"prev":{"headline":"net/mlx5e: Don't clone flow post action attributes second time","id":"CVE-2023-54262"},"products":["Linux"],"published":"2025-12-30","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":"2026-09-02","vendors":["Linux"]},"summary":"A missing lock initialization in the nouveau driver causes a kernel OOPS on systems with ANX9805 DP encoders, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2023-54263/"}
