If\nirq_create_mapping() fails, port->intx_irq stays initialized.\n\nHence, remove the IRQ domains in the error path by calling\nplda_pcie_irq_domain_deinit().\n\nSince plda_pcie_irq_domain_deinit() now disposes of the intx_irq and\nmsi_irq mappings itself before removing their domains, the msi_irq\nmapping failure path can go directly to err_irq_domain_deinit instead of\ndisposing of port->intx_irq separately first.\n\nThis issue was found by automated review of sashiko-bot\n\n[mani: commit log]","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/01b05cebe1e862e31e382359848d7dca02525a4f","https://git.kernel.org/stable/c/19a30bbb6477bfd7e3109b7a2943e6597ee9de37","https://git.kernel.org/stable/c/4b575052ea65423693726a21826d783cf3f1745e","https://git.kernel.org/stable/c/e54e8d2a0f9c8bf251ae4385ea4f4a68840fedad"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-89454","score":0.00206,"percentile":0.1046,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
