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-2026-53297 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-2026-53297/ (Markdown: https://insights.sbomify.com/CVE-2026-53297/index.md)","id":"CVE-2026-53297","markdown":"https://insights.sbomify.com/CVE-2026-53297/index.md","name":"CVE-2026-53297","record":{"aliases":["AZL-91331","BELL-CVE-2026-53297","DEBIAN-CVE-2026-53297","GHSA-43rv-4q7x-r3cg","ROOT-OS-DEBIAN-12-CVE-2026-53297","ROOT-OS-DEBIAN-13-CVE-2026-53297","ROOT-OS-UBUNTU-2404-CVE-2026-53297","UBUNTU-CVE-2026-53297"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A double invocation of the mana_remove function in the Linux kernel network driver causes a null pointer dereference, leading to a kernel panic and 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-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: mana: Guard mana_remove against double invocation\n\nIf PM resume fails (e.g., mana_attach() returns an error), mana_probe()\ncalls mana_remove(), which tears down the device and sets\ngd-\u003egdma_context = NULL and gd-\u003edriver_data = NULL.\n\nHowever, a failed resume callback does not automatically unbind the\ndriver.
