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-2024-26831 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-2024-26831/ (Markdown: https://insights.sbomify.com/CVE-2024-26831/index.md)","id":"CVE-2024-26831","markdown":"https://insights.sbomify.com/CVE-2024-26831/index.md","name":"CVE-2024-26831","record":{"aliases":["BELL-CVE-2024-26831","DEBIAN-CVE-2024-26831","GHSA-mmcw-f5qh-65q3","UBUNTU-CVE-2024-26831"],"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 handshake subsystem caused a use-after-free or null pointer dereference during test cleanup, potentially leading to system instability.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet/handshake: Fix handshake_req_destroy_test1\n\nRecently, handshake_req_destroy_test1 started failing:\n\nExpected handshake_req_destroy_test == req, but\n    handshake_req_destroy_test == 0000000000000000\n    req == 0000000060f99b40\nnot ok 11 req_destroy works\n\nThis is because \"sock_release(sock)\" was replaced with \"fput(filp)\"\nto address a memory leak.
