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-2025-38459 in the wild and no public exploit code.\n\nAffected product: Debian Debian 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-2025-38459/ (Markdown: https://insights.sbomify.com/CVE-2025-38459/index.md)","id":"CVE-2025-38459","markdown":"https://insights.sbomify.com/CVE-2025-38459/index.md","name":"CVE-2025-38459","record":{"aliases":["AZL-65822","AZL-72941","BELL-CVE-2025-38459","DEBIAN-CVE-2025-38459","GHSA-4qp6-h6gx-pgm5","ROOT-OS-DEBIAN-11-CVE-2025-38459","ROOT-OS-DEBIAN-12-CVE-2025-38459","ROOT-OS-UBUNTU-2204-CVE-2025-38459","ROOT-OS-UBUNTU-2404-CVE-2025-38459","UBUNTU-CVE-2025-38459"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel ATM","requires_auth":"low_privilege","summary":"A local attacker can trigger infinite recursion in the Linux kernel ATM subsystem via repeated ioctl calls, causing a stack overflow and system crash.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","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-787","name":"Out-of-bounds Write"},{"id":"CWE-674","name":"Uncontrolled Recursion"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\natm: clip: Fix infinite recursive call of clip_push().\n\nsyzbot reported the splat below. [0]\n\nThis happens if we call ioctl(ATMARP_MKIP) more than once.\n\nDuring the first call, clip_mkip() sets clip_push() to vcc-\u003epush(),\nand the second call copies it to clip_vcc-\u003eold_push().\n\nLater, when the socket is close()d, vcc_destroy_socket() passes\nNULL skb to clip_push(), which calls clip_vcc-\u003eold_push(),\ntriggering the infinite recursion.\n\nLet's prevent the second ioctl(ATMARP_MKIP) by checking\nvcc-\u003euser_back, which is allocated by the first call as clip_vcc.\n\nNote also that we use lock_sock() to prevent racy calls.\n\n[0]:\nBUG: TASK stack guard page was hit at ffffc9000d66fff8 (stack is ffffc9000d670000..ffffc9000d678000)\nOops: stack guard page: 0000 [#1] SMP KASAN NOPTI\nCPU: 0 UID: 0 PID: 5322 Comm:
