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-2025-68333 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-2025-68333/ (Markdown: https://insights.sbomify.com/CVE-2025-68333/index.md)","id":"CVE-2025-68333","markdown":"https://insights.sbomify.com/CVE-2025-68333/index.md","name":"CVE-2025-68333","record":{"aliases":["BELL-CVE-2025-68333","DEBIAN-CVE-2025-68333","GHSA-xw74-3hjf-3xpv","ROOT-OS-DEBIAN-13-CVE-2025-68333","ROOT-OS-UBUNTU-2204-CVE-2025-68333","ROOT-OS-UBUNTU-2404-CVE-2025-68333","UBUNTU-CVE-2025-68333"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel's sched_ext subsystem can cause a deadlock in PREEMPT_RT kernels, leading to denial of service.","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":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-667","name":"Improper Locking"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nsched_ext: Fix possible deadlock in the deferred_irq_workfn()\n\nFor PREEMPT_RT=y kernels, the deferred_irq_workfn() is executed in\nthe per-cpu irq_work/* task context and not disable-irq, if the rq\nreturned by container_of() is current CPU's rq, the following scenarios\nmay occur:\n\nlock(\u0026rq-\u003e__lock);\n\u003cInterrupt\u003e\n  lock(\u0026rq-\u003e__lock);\n\nThis commit use IRQ_WORK_INIT_HARD() to replace init_irq_work() to\ninitialize rq-\u003escx.deferred_irq_work, make the deferred_irq_workfn()\nis always invoked in hard-irq context.","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":"sched_ext: Fix possible deadlock in the deferred_irq_workfn()","id":"CVE-2025-68333","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"race_condition","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"platform/x86/amd/pmc: Add support for Van Gogh SoC","id":"CVE-2025-68334"},"packages":[],"prev":{"headline":"comedi: c6xdigio: Fix invalid PNP driver unregistration","id":"CVE-2025-68332"},"products":["Linux"],"published":"2025-12-22","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A race condition in the Linux kernel's sched_ext subsystem can cause a deadlock in PREEMPT_RT kernels, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2025-68333/"}
