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-2026-53156 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-2026-53156/ (Markdown: https://insights.sbomify.com/CVE-2026-53156/index.md)","id":"CVE-2026-53156","markdown":"https://insights.sbomify.com/CVE-2026-53156/index.md","name":"CVE-2026-53156","record":{"aliases":["AZL-90480","BELL-CVE-2026-53156","DEBIAN-CVE-2026-53156","GHSA-2wqp-vx6w-rvfx","ROOT-OS-DEBIAN-11-CVE-2026-53156","ROOT-OS-DEBIAN-12-CVE-2026-53156","ROOT-OS-UBUNTU-2204-CVE-2026-53156","ROOT-OS-UBUNTU-2404-CVE-2026-53156","UBUNTU-CVE-2026-53156"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel nvmem core allows attackers to potentially execute code or escalate privileges via error paths.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"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-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnvmem: core: fix use-after-free bugs in error paths\n\nFix several instances of error paths in which we call\n__nvmem_device_put() - which may end up freeing the underlying memory\nand other resources - and then keep on using the nvmem structure.
