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-2026-90331 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-2026-90331/ (Markdown: https://insights.sbomify.com/CVE-2026-90331/index.md)","id":"CVE-2026-90331","markdown":"https://insights.sbomify.com/CVE-2026-90331/index.md","name":"CVE-2026-90331","record":{"aliases":["DEBIAN-CVE-2026-90331","GHSA-crc6-vh29-6g24","UBUNTU-CVE-2026-90331"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A use-after-free vulnerability in the Linux kernel HID ASUS driver allows local attackers to execute arbitrary code or escalate privileges.","user_interaction":"not_required","vuln_class":"use_after_free"},"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\nHID: asus: refactor the two workqueues and init sequence\n\nMultiple issues have been found within the hid-asus driver:\n- unchecked size in asus_raw_event()\n- unclean teardown of asus_probe on failure\n- possible use-after-free in asus_probe\n- multiple workqueue used for jobs where one was enough\n- sleeping calls in atomic context\n- packets of incorrect size being sent to the keyboard controller\n\nJoin the two workqueues into one reusing the stopping mechanism\nof the brightness workqueue, use the joined workqueue to also\nmove the asus_wmi_send_event() sleeping call away from atomic\ncontext and add a size check in asus_raw_event().","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"HID: asus: refactor the two workqueues and init sequence","id":"CVE-2026-90331","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"PCI: dwc: ep: Flush cached MSI write before unmapping the iATU","id":"CVE-2026-90332"},"packages":[],"prev":{"headline":"HID: logitech-hidpp: Fix FF device cleanup on init failure","id":"CVE-2026-90330"},"products":["Linux"],"published":"2026-09-17","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel HID ASUS driver allows local attackers to execute arbitrary code or escalate privileges.","url":"https://insights.sbomify.com/CVE-2026-90331/"}
