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-2026-98066 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-2026-98066/ (Markdown: https://insights.sbomify.com/CVE-2026-98066/index.md)","id":"CVE-2026-98066","markdown":"https://insights.sbomify.com/CVE-2026-98066/index.md","name":"CVE-2026-98066","record":{"aliases":["AZL-104322","BELL-CVE-2026-98066","DEBIAN-CVE-2026-98066","GHSA-m4v8-qp6h-hh9w","UBUNTU-CVE-2026-98066"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A double-free vulnerability in the Linux kernel ALSA caiaq driver allows local attackers to cause denial of service or potentially 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\nALSA: caiaq: Fix potential double-free at error path\n\nThe fix for caiaq driver's resource management to handle the errors\ntries to release the resources in a common destructor call, but as a\nsashiko review for another patch suggested, some of the audio\nresources such as URBs have been already freed, and this may lead to a\ndouble-free.\n\nFor addressing the double-free, call the common destructor function\nfrom each place, and assure that the resource pointers get cleared.","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":"ALSA: caiaq: Fix potential double-free at error path","id":"CVE-2026-98066","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"erofs: disable LZ4 rolling decompression for now","id":"CVE-2026-98067"},"packages":[],"prev":{"headline":"bpf: Reject key-less BTF for hash maps","id":"CVE-2026-98065"},"products":["Linux"],"published":"2026-09-25","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 double-free vulnerability in the Linux kernel ALSA caiaq driver allows local attackers to cause denial of service or potentially escalate privileges.","url":"https://insights.sbomify.com/CVE-2026-98066/"}
