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-2025-38544 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-2025-38544/ (Markdown: https://insights.sbomify.com/CVE-2025-38544/index.md)","id":"CVE-2025-38544","markdown":"https://insights.sbomify.com/CVE-2025-38544/index.md","name":"CVE-2025-38544","record":{"aliases":["AZL-66380","AZL-70457","BELL-CVE-2025-38544","DEBIAN-CVE-2025-38544","GHSA-2fgf-j87m-qgrf","ROOT-OS-DEBIAN-11-CVE-2025-38544","ROOT-OS-DEBIAN-12-CVE-2025-38544","ROOT-OS-UBUNTU-2204-CVE-2025-38544","ROOT-OS-UBUNTU-2404-CVE-2025-38544","UBUNTU-CVE-2025-38544"],"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 bug in the Linux kernel's rxrpc module causes assertion failures during error handling, potentially leading to a denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-617","name":"Reachable Assertion"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nrxrpc: Fix bug due to prealloc collision\n\nWhen userspace is using AF_RXRPC to provide a server, it has to preallocate\nincoming calls and assign to them call IDs that will be used to thread\nrelated recvmsg() and sendmsg() together.  The preallocated call IDs will\nautomatically be attached to calls as they come in until the pool is empty.\n\nTo the kernel, the call IDs are just arbitrary numbers, but userspace can\nuse the call ID to hold a pointer to prepared structs.
