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-2026-80911 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-2026-80911/ (Markdown: https://insights.sbomify.com/CVE-2026-80911/index.md)","id":"CVE-2026-80911","markdown":"https://insights.sbomify.com/CVE-2026-80911/index.md","name":"CVE-2026-80911","record":{"aliases":["AZL-99470","BELL-CVE-2026-80911","DEBIAN-CVE-2026-80911","GHSA-v4fw-33v9-5mm7","UBUNTU-CVE-2026-80911"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel audio","requires_auth":"none","summary":"A double decrement of use_count in the Linux kernel SOF audio driver can lead to a use-after-free condition, potentially causing a system crash.","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\nASoC: SOF: sof-audio: Fix error path in sof_widget_setup_unlocked()\n\nIf either tplg_ops-\u003edai_config or widget_kcontrol_setup fail during widget\nsetup we would double decrement the use_count of the widget because the\nsof_widget_free_unlocked() would be called twice, similarly the core_put\nwould be invoked twice as well.\n\nSince the use_count and core_put() is handled within the widget_free\nfunction we need to return without falling through the pipe_widget_free\nlabel.\n\nThe fixes tag is picked to the last change around this part of the code\nwhich is adequately old enough for backporting purposes.","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":"ASoC: SOF: sof-audio: Fix error path in sof_widget_setup_unlocked()","id":"CVE-2026-80911","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"selinux: reject an unclaimed class value in security_get_classes()","id":"CVE-2026-80912"},"packages":[],"prev":{"headline":"ASoC: codecs: lpass-wsa-macro: Fix enum kcontrol accesses","id":"CVE-2026-80910"},"products":["Linux"],"published":"2026-09-04","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":"2026-09-04","vendors":["Linux"]},"summary":"A double decrement of use_count in the Linux kernel SOF audio driver can lead to a use-after-free condition, potentially causing a system crash.","url":"https://insights.sbomify.com/CVE-2026-80911/"}
