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-2026-90158 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-2026-90158/ (Markdown: https://insights.sbomify.com/CVE-2026-90158/index.md)","id":"CVE-2026-90158","markdown":"https://insights.sbomify.com/CVE-2026-90158/index.md","name":"CVE-2026-90158","record":{"aliases":["AZL-102012","BELL-CVE-2026-90158","DEBIAN-CVE-2026-90158","GHSA-fwv7-hfpv-34gj","UBUNTU-CVE-2026-90158"],"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":"none","summary":"A deadlock in the Linux kernel m68k nfcon driver causes a denial of service when console registration functions are called concurrently.","user_interaction":"not_required","vuln_class":"race_condition"},"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\nm68k: nfcon: Do not call console_is_registered() in nfcon_device()\n\nSince 7c2af0f634f1 (\"tty: tty_io: use console_list_lock for list\nsynchronization\") show_cons_active() calls the .device() method under\nthe console_list_lock, but console_is_registered() tries to acquire\nconsole_list_lock as well, causing a deadlock.
