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-2026-80966 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-2026-80966/ (Markdown: https://insights.sbomify.com/CVE-2026-80966/index.md)","id":"CVE-2026-80966","markdown":"https://insights.sbomify.com/CVE-2026-80966/index.md","name":"CVE-2026-80966","record":{"aliases":["AZL-100620","BELL-CVE-2026-80966","DEBIAN-CVE-2026-80966","GHSA-q972-jx45-qf27","UBUNTU-CVE-2026-80966"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"high_privilege","summary":"A missing check in the ALSA portman2x4 driver allows out-of-bounds access, potentially causing crashes or information leaks for local attackers.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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: portman2x4: Check card index validity at probe\n\nAlthough portman2x4 driver has a check of the given devptr-\u003eid value,\nit doesn't check for a negative id, which is often given as \"none\" or\nsuch value when bound via sysfs.
