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-2023-54279 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-2023-54279/ (Markdown: https://insights.sbomify.com/CVE-2023-54279/index.md)","id":"CVE-2023-54279","markdown":"https://insights.sbomify.com/CVE-2023-54279/index.md","name":"CVE-2023-54279","record":{"aliases":["BELL-CVE-2023-54279","DEBIAN-CVE-2023-54279","GHSA-fp2g-4w3c-p2mv","UBUNTU-CVE-2023-54279"],"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":"none","summary":"A null pointer dereference in the MIPS firmware environment handling allows local attackers to cause a denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"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\nMIPS: fw: Allow firmware to pass a empty env\n\nfw_getenv will use env entry to determine style of env,\nhowever it is legal for firmware to just pass a empty list.\n\nCheck if first entry exist before running strchr to avoid\nnull pointer dereference.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"MIPS: fw: Allow firmware to pass a empty env","id":"CVE-2023-54279","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2023"},"n_packages":0,"n_references":9,"next":{"headline":"cifs: fix potential race when tree connecting ipc","id":"CVE-2023-54280"},"packages":[],"prev":{"headline":"s390/vmem: split pages when debug pagealloc is enabled","id":"CVE-2023-54278"},"products":["Linux"],"published":"2025-12-30","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A null pointer dereference in the MIPS firmware environment handling allows local attackers to cause a denial of service.","url":"https://insights.sbomify.com/CVE-2023-54279/"}
