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-2023-53218 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2023-53218/ (Markdown: https://insights.sbomify.com/CVE-2023-53218/index.md)","id":"CVE-2023-53218","markdown":"https://insights.sbomify.com/CVE-2023-53218/index.md","name":"CVE-2023-53218","record":{"aliases":["AZL-71227","BELL-CVE-2023-53218","DEBIAN-CVE-2023-53218","GHSA-749j-m4j7-mhr2","ROOT-OS-DEBIAN-11-CVE-2023-53218","ROOT-OS-DEBIAN-12-CVE-2023-53218","ROOT-OS-UBUNTU-2204-CVE-2023-53218","UBUNTU-CVE-2023-53218"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A flaw in the Linux kernel's rxrpc module allows a waiting process to hang indefinitely, causing a denial of service until patched.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nrxrpc: Make it so that a waiting process can be aborted\n\nWhen sendmsg() creates an rxrpc call, it queues it to wait for a connection\nand channel to be assigned and then waits before it can start shovelling\ndata as the encrypted DATA packet content includes a summary of the\nconnection parameters.\n\nHowever, sendmsg() may get interrupted before a connection gets assigned\nand further sendmsg() calls will fail with EBUSY until an assignment is\nmade.\n\nFix this so that the call can at least be aborted without failing on\nEBUSY.
