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-2026-90027 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-2026-90027/ (Markdown: https://insights.sbomify.com/CVE-2026-90027/index.md)","id":"CVE-2026-90027","markdown":"https://insights.sbomify.com/CVE-2026-90027/index.md","name":"CVE-2026-90027","record":{"aliases":["AZL-101666","BELL-CVE-2026-90027","DEBIAN-CVE-2026-90027","GHSA-fm22-hcrq-m39w","UBUNTU-CVE-2026-90027"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel USB driver","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel's Qualcomm PMIC Type-C driver allows attackers to cause denial of service or execute code via race conditions during port stop.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nusb: typec: qcom-pmic-typec: disable cc_debounce_dwork on stop\n\ncc_debounce_dwork is queued from the set_cc() and start_toggling()\ncallbacks, which run from TCPM's kthread worker.  port_stop() returns\nbefore tcpm_unregister_port() destroys that worker.
