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-2025-37761 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-2025-37761/ (Markdown: https://insights.sbomify.com/CVE-2025-37761/index.md)","id":"CVE-2025-37761","markdown":"https://insights.sbomify.com/CVE-2025-37761/index.md","name":"CVE-2025-37761","record":{"aliases":["BELL-CVE-2025-37761","DEBIAN-CVE-2025-37761","GHSA-mmv8-63hv-mhrh","ROOT-OS-UBUNTU-2404-CVE-2025-37761","UBUNTU-CVE-2025-37761"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A local attacker can trigger a kernel crash via an out-of-bounds shift in the Intel Xe GPU driver during TLB invalidation.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/xe: Fix an out-of-bounds shift when invalidating TLB\n\nWhen the size of the range invalidated is larger than\nrounddown_pow_of_two(ULONG_MAX),\nThe function macro roundup_pow_of_two(length) will hit an out-of-bounds\nshift [1].\n\nUse a full TLB invalidation for such cases.\nv2:\n- Use a define for the range size limit over which we use a full\n  TLB invalidation.
