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-2023-53214 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-2023-53214/ (Markdown: https://insights.sbomify.com/CVE-2023-53214/index.md)","id":"CVE-2023-53214","markdown":"https://insights.sbomify.com/CVE-2023-53214/index.md","name":"CVE-2023-53214","record":{"aliases":["BELL-CVE-2023-53214","DEBIAN-CVE-2023-53214","GHSA-x74x-w5qg-98qh","UBUNTU-CVE-2023-53214"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A buffer overflow in the Linux kernel's f2fs filesystem allows attackers to cause memory corruption, potentially leading to code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nf2fs: fix to avoid potential memory corruption in __update_iostat_latency()\n\nAdd iotype sanity check to avoid potential memory corruption.\nThis is to fix the compile error below:\n\nfs/f2fs/iostat.c:231 __update_iostat_latency() error: buffer overflow\n'io_lat-\u003epeak_lat[type]' 3 \u003c= 3\n\nvim +228 fs/f2fs/iostat.c\n\n  211  static inline void __update_iostat_latency(struct bio_iostat_ctx\n\t*iostat_ctx,\n  212\t\t\t\t\tenum iostat_lat_type type)\n  213  {\n  214\t\tunsigned long ts_diff;\n  215\t\tunsigned int page_type = iostat_ctx-\u003etype;\n  216\t\tstruct f2fs_sb_info *sbi = iostat_ctx-\u003esbi;\n  217\t\tstruct iostat_lat_info *io_lat = sbi-\u003eiostat_io_lat;\n  218\t\tunsigned long flags;\n  219\n  220\t\tif (!sbi-\u003eiostat_enable)\n  221\t\t\treturn;\n  222\n  223\t\tts_diff = jiffies -
