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-2024-50017 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-2024-50017/ (Markdown: https://insights.sbomify.com/CVE-2024-50017/index.md)","id":"CVE-2024-50017","markdown":"https://insights.sbomify.com/CVE-2024-50017/index.md","name":"CVE-2024-50017","record":{"aliases":["AZL-51342","AZL-51497","BELL-CVE-2024-50017","DEBIAN-CVE-2024-50017","GHSA-h8wp-xf43-pm3w","ROOT-OS-DEBIAN-11-CVE-2024-50017","ROOT-OS-DEBIAN-12-CVE-2024-50017","ROOT-OS-UBUNTU-2204-CVE-2024-50017","UBUNTU-CVE-2024-50017"],"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 flaw in Linux kernel identity mapping allows processor speculation into reserved regions, potentially causing system halts on UV systems.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nx86/mm/ident_map: Use gbpages only where full GB page should be mapped.\n\nWhen ident_pud_init() uses only GB pages to create identity maps, large\nranges of addresses not actually requested can be included in the resulting\ntable; a 4K request will map a full GB.
