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-2026-98565 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2026-98565/ (Markdown: https://insights.sbomify.com/CVE-2026-98565/index.md)","id":"CVE-2026-98565","markdown":"https://insights.sbomify.com/CVE-2026-98565/index.md","name":"CVE-2026-98565","record":{"aliases":["AZL-109307","BELL-CVE-2026-98565","DEBIAN-CVE-2026-98565","GHSA-4r34-63x3-rq2x","UBUNTU-CVE-2026-98565"],"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":"high_privilege","summary":"A local attacker with root privileges can cause a kernel crash by unbinding the MT7531 or MT7621 DSA driver due to a NULL pointer dereference.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: dsa: mt7530: fix NULL dereference on unbind of MT7531 and MT7621\n\nThe core and io supplies are only requested for ID_MT7530: both the\ndevm_regulator_get() in probe and the regulator_enable() in\nmt7530_setup() are guarded by the switch id, but mt7530_remove()\ndisables them unconditionally.
