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-2023-54146 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-2023-54146/ (Markdown: https://insights.sbomify.com/CVE-2023-54146/index.md)","id":"CVE-2023-54146","markdown":"https://insights.sbomify.com/CVE-2023-54146/index.md","name":"CVE-2023-54146","record":{"aliases":["BELL-CVE-2023-54146","DEBIAN-CVE-2023-54146","GHSA-wg2w-8j36-3rqh","UBUNTU-CVE-2023-54146"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"high_privilege","summary":"A double-free vulnerability in the Linux kernel's kexec subsystem allows local attackers to cause denial of service or potentially escalate privileges.","user_interaction":"not_required","vuln_class":"use_after_free"},"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\nx86/kexec: Fix double-free of elf header buffer\n\nAfter\n\n  b3e34a47f989 (\"x86/kexec: fix memory leak of elf header buffer\"),\n\nfreeing image-\u003eelf_headers in the error path of crash_load_segments()\nis not needed because kimage_file_post_load_cleanup() will take\ncare of that later.
