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-2025-37838 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-2025-37838/ (Markdown: https://insights.sbomify.com/CVE-2025-37838/index.md)","id":"CVE-2025-37838","markdown":"https://insights.sbomify.com/CVE-2025-37838/index.md","name":"CVE-2025-37838","record":{"aliases":["BELL-CVE-2025-37838","DEBIAN-CVE-2025-37838","GHSA-m8p9-q552-5h79","ROOT-OS-UBUNTU-2204-CVE-2025-37838","ROOT-OS-UBUNTU-2404-CVE-2025-37838","UBUNTU-CVE-2025-37838"],"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 driver","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel HSI ssi_protocol driver allows a use-after-free, potentially enabling local attackers to execute 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\nHSI: ssi_protocol: Fix use after free vulnerability in ssi_protocol Driver Due to Race Condition\n\nIn the ssi_protocol_probe() function, \u0026ssi-\u003ework is bound with\nssip_xmit_work(), In ssip_pn_setup(), the ssip_pn_xmit() function\nwithin the ssip_pn_ops structure is capable of starting the\nwork.\n\nIf we remove the module which will call ssi_protocol_remove()\nto make a cleanup, it will free ssi through kfree(ssi),\nwhile the work mentioned above will be used.
