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-2026-45964 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-2026-45964/ (Markdown: https://insights.sbomify.com/CVE-2026-45964/index.md)","id":"CVE-2026-45964","markdown":"https://insights.sbomify.com/CVE-2026-45964/index.md","name":"CVE-2026-45964","record":{"aliases":["BELL-CVE-2026-45964","DEBIAN-CVE-2026-45964","GHSA-7m86-h2jr-vw87","ROOT-OS-UBUNTU-2204-CVE-2026-45964","ROOT-OS-UBUNTU-2404-CVE-2026-45964","UBUNTU-CVE-2026-45964"],"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 memory leak in the Linux kernel SUNRPC module can lead to resource exhaustion and denial of service when specific error paths are triggered.","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\nSUNRPC: fix gss_auth kref leak in gss_alloc_msg error path\n\nCommit 5940d1cf9f42 (\"SUNRPC: Rebalance a kref in auth_gss.c\") added\na kref_get(\u0026gss_auth-\u003ekref) call to balance the gss_put_auth() done\nin gss_release_msg(), but forgot to add a corresponding kref_put()\non the error path when kstrdup_const() fails.\n\nIf service_name is non-NULL and kstrdup_const() fails, the function\njumps to err_put_pipe_version which calls put_pipe_version() and\nkfree(gss_msg), but never releases the gss_auth reference.
