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-2026-64462 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-2026-64462/ (Markdown: https://insights.sbomify.com/CVE-2026-64462/index.md)","id":"CVE-2026-64462","markdown":"https://insights.sbomify.com/CVE-2026-64462/index.md","name":"CVE-2026-64462","record":{"aliases":["AZL-93786","BELL-CVE-2026-64462","DEBIAN-CVE-2026-64462","GHSA-w9v7-p38p-x494","ROOT-OS-UBUNTU-2204-CVE-2026-64462","UBUNTU-CVE-2026-64462"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"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 Altera PCI driver allows local attackers to cause denial of service or potentially execute code via probe failure.","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\nPCI: altera: Fix resource leaks on probe failure\n\nThe chained IRQ handler is set during probe, but is only removed during the\ndriver remove().
