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-2026-89454 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-2026-89454/ (Markdown: https://insights.sbomify.com/CVE-2026-89454/index.md)","id":"CVE-2026-89454","markdown":"https://insights.sbomify.com/CVE-2026-89454/index.md","name":"CVE-2026-89454","record":{"aliases":["BELL-CVE-2026-89454","DEBIAN-CVE-2026-89454","GHSA-ww3r-fjgm-2rcq","UBUNTU-CVE-2026-89454"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel PCI driver","requires_auth":"none","summary":"A resource leak in the Linux kernel PCI driver allows local attackers to exhaust system resources, potentially causing denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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: plda: Fix IRQ domain leaks in the error paths of plda_init_interrupts()\n\nplda_init_interrupts() initializes IRQ domains and creates IRQ mapping but\ndoes not unwind them when later step fails.\n\nIf platform_get_irq() or either irq_create_mapping() fails\nin plda_init_interrupts(), the domains are never deinitialized.
