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-2023-4622 in the wild and no public exploit code.\n\nAffected product: Debian Debian 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-2023-4622/ (Markdown: https://insights.sbomify.com/CVE-2023-4622/index.md)","id":"CVE-2023-4622","markdown":"https://insights.sbomify.com/CVE-2023-4622/index.md","name":"CVE-2023-4622","record":{"aliases":["A-299123598","ASB-A-299123598","AZL-28679","AZL-31642","DEBIAN-CVE-2023-4622","GHSA-hxpr-87wq-jwf8","SUSE-SU-2023:4795-1","SUSE-SU-2023:4799-1","SUSE-SU-2023:4831-1","SUSE-SU-2023:4847-1","UBUNTU-CVE-2023-4622"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A use-after-free in the Linux kernel's af_unix component allows local attackers to escalate privileges due to a race condition.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Google","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"A use-after-free vulnerability in the Linux kernel's af_unix component can be exploited to achieve local privilege escalation.\n\nThe unix_stream_sendpage() function tries to add data to the last skb in the peer's recv queue without locking the queue.
