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-2023-53429 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-2023-53429/ (Markdown: https://insights.sbomify.com/CVE-2023-53429/index.md)","id":"CVE-2023-53429","markdown":"https://insights.sbomify.com/CVE-2023-53429/index.md","name":"CVE-2023-53429","record":{"aliases":["AZL-71921","BELL-CVE-2023-53429","DEBIAN-CVE-2023-53429","GHSA-95qf-frmh-4g6j","ROOT-OS-DEBIAN-11-CVE-2023-53429","ROOT-OS-DEBIAN-12-CVE-2023-53429","ROOT-OS-UBUNTU-2204-CVE-2023-53429","UBUNTU-CVE-2023-53429"],"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 race condition in the Linux kernel's btrfs filesystem allows error bits to leak, potentially causing system instability or crashes.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: don't check PageError in __extent_writepage\n\n__extent_writepage currenly sets PageError whenever any error happens,\nand the also checks for PageError to decide if to call error handling.\nThis leads to very unclear responsibility for cleaning up on errors.\nIn the VM and generic writeback helpers the basic idea is that once\nI/O is fired off all error handling responsibility is delegated to the\nend I/O handler.
