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-2026-90367 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-2026-90367/ (Markdown: https://insights.sbomify.com/CVE-2026-90367/index.md)","id":"CVE-2026-90367","markdown":"https://insights.sbomify.com/CVE-2026-90367/index.md","name":"CVE-2026-90367","record":{"aliases":["AZL-102164","BELL-CVE-2026-90367","DEBIAN-CVE-2026-90367","GHSA-rjqr-mg4v-422g","UBUNTU-CVE-2026-90367"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel WiFi driver","requires_auth":"none","summary":"A race condition in the mt7996 WiFi driver can corrupt DMA descriptors during reset, potentially causing system instability or denial of service.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/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\nwifi: mt76: mt7996: hold dev-\u003emt76.mutex while disabling tx worker in SER\n\nmt7996_mac_reset_work() parked the tx worker and disabled the RX/TX NAPIs\nbefore taking dev-\u003emt76.mutex. mt76_worker_disable()/_enable() are plain\nkthread park/unpark, not refcounted, and __mt76_set_channel() toggles the\nsame worker and the MT76_RESET bit under the mutex.
