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-2025-37845 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-2025-37845/ (Markdown: https://insights.sbomify.com/CVE-2025-37845/index.md)","id":"CVE-2025-37845","markdown":"https://insights.sbomify.com/CVE-2025-37845/index.md","name":"CVE-2025-37845","record":{"aliases":["BELL-CVE-2025-37845","DEBIAN-CVE-2025-37845","GHSA-mjp6-8q33-2qx3","ROOT-OS-UBUNTU-2204-CVE-2025-37845","UBUNTU-CVE-2025-37845"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel's fprobe events allows attackers to potentially execute arbitrary code or escalate privileges.","user_interaction":"not_required","vuln_class":"use_after_free"},"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-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ntracing: fprobe events: Fix possible UAF on modules\n\nCommit ac91052f0ae5 (\"tracing: tprobe-events: Fix leakage of module\nrefcount\") moved try_module_get() from __find_tracepoint_module_cb()\nto find_tracepoint() caller, but that introduced a possible UAF\nbecause the module can be unloaded before try_module_get().
