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-2023-54268 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-2023-54268/ (Markdown: https://insights.sbomify.com/CVE-2023-54268/index.md)","id":"CVE-2023-54268","markdown":"https://insights.sbomify.com/CVE-2023-54268/index.md","name":"CVE-2023-54268","record":{"aliases":["BELL-CVE-2023-54268","DEBIAN-CVE-2023-54268","GHSA-wfjg-crvw-f25h","UBUNTU-CVE-2023-54268"],"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 locking issue in the Linux kernel debugobjects subsystem can cause a deadlock or system hang when memory allocation triggers kswapd wakeups.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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\ndebugobjects: Don't wake up kswapd from fill_pool()\n\nsyzbot is reporting a lockdep warning in fill_pool() because the allocation\nfrom debugobjects is using GFP_ATOMIC, which is (__GFP_HIGH | __GFP_KSWAPD_RECLAIM)\nand therefore tries to wake up kswapd, which acquires kswapd_wait::lock.\n\nSince fill_pool() might be called with arbitrary locks held, fill_pool()\nshould not assume that acquiring kswapd_wait::lock is safe.\n\nUse __GFP_HIGH instead and remove __GFP_NORETRY as it is pointless for\n!__GFP_DIRECT_RECLAIM allocation.","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":"debugobjects: Don't wake up kswapd from fill_pool()","id":"CVE-2023-54268","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":6,"next":{"headline":"SUNRPC: double free xprt_ctxt while still in use","id":"CVE-2023-54269"},"packages":[],"prev":{"headline":"powerpc/pseries: Rework lppaca_shared_proc() to avoid DEBUG_PREEMPT","id":"CVE-2023-54267"},"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 locking issue in the Linux kernel debugobjects subsystem can cause a deadlock or system hang when memory allocation triggers kswapd wakeups.","url":"https://insights.sbomify.com/CVE-2023-54268/"}
