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-2026-74273 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-2026-74273/ (Markdown: https://insights.sbomify.com/CVE-2026-74273/index.md)","id":"CVE-2026-74273","markdown":"https://insights.sbomify.com/CVE-2026-74273/index.md","name":"CVE-2026-74273","record":{"aliases":["AZL-110426","BELL-CVE-2026-74273","DEBIAN-CVE-2026-74273","GHSA-447m-c2m6-7v5x","UBUNTU-CVE-2026-74273"],"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":"low_privilege","summary":"A race condition in the Linux kernel CXL region driver allows local users to trigger a denial of service by deleting regions during creation.","user_interaction":"not_required","vuln_class":"race_condition"},"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\ncxl/region: Block region delete during region creation\n\nExpand the range lock, rename it \"regions_lock\", to disable region deletion\nin the critical period between construct_region() and attach_target(), as\nwell as the period between device_add() and registering the remove actions.\n\nOtherwise, userspace can confuse the kernel.
