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-2025-37920 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-2025-37920/ (Markdown: https://insights.sbomify.com/CVE-2025-37920/index.md)","id":"CVE-2025-37920","markdown":"https://insights.sbomify.com/CVE-2025-37920/index.md","name":"CVE-2025-37920","record":{"aliases":["AZL-62598","AZL-69941","BELL-CVE-2025-37920","DEBIAN-CVE-2025-37920","GHSA-4qc6-52f6-6vgr","ROOT-OS-DEBIAN-11-CVE-2025-37920","ROOT-OS-DEBIAN-12-CVE-2025-37920","ROOT-OS-UBUNTU-2204-CVE-2025-37920","ROOT-OS-UBUNTU-2404-CVE-2025-37920","UBUNTU-CVE-2025-37920"],"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 race condition in the Linux kernel's AF_XDP generic RX path allows concurrent access issues, potentially leading to system instability or denial of service.","user_interaction":"not_required","vuln_class":"race_condition"},"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-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nxsk: Fix race condition in AF_XDP generic RX path\n\nMove rx_lock from xsk_socket to xsk_buff_pool.\nFix synchronization for shared umem mode in\ngeneric RX path where multiple sockets share\nsingle xsk_buff_pool.\n\nRX queue is exclusive to xsk_socket, while FILL\nqueue can be shared between multiple sockets.\nThis could result in race condition where two\nCPU cores access RX path of two different sockets\nsharing the same umem.\n\nProtect both queues by acquiring spinlock in shared\nxsk_buff_pool.\n\nLock contention may be minimized in the future by some\nper-thread FQ buffering.\n\nIt's safe and necessary to move spin_lock_bh(rx_lock)\nafter xsk_rcv_check():\n* xs-\u003epool and spinlock_init is synchronized by\n  xsk_bind() -\u003e xsk_is_bound() memory barriers.\n* xsk_rcv_check() may return true at the moment\n  of xsk_release() or xsk_unbind_dev(),\n  however this will not cause any data races or\n  race conditions. xsk_unbind_dev() removes xdp\n  socket from all maps and waits for completion\n  of all outstanding rx operations.
