If pci_host_probe() fails, the handler and INTx IRQ\ndomain remain set even though the devm-managed host bridge storage\ncontaining struct altera_pcie will be released, leaving the handler with\na stale data pointer.\n\nInterrupts are also enabled before pci_host_probe() is called. If probe\nfails after that point, the controller interrupt source should be disabled\nbefore the chained handler and INTx domain are removed.\n\nSo set the chained handler only after the INTx domain has been created.\nDisable controller interrupts during IRQ teardown, and tear the IRQ setup\ndown if pci_host_probe() fails.\n\n[mani: commit log]","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/09c43b7b7d29c6fadb27f32cdf7f3bb6598befa9","https://git.kernel.org/stable/c/0db9aa9ec51be0a0ffdcdfd9af2b7bf3aeb7911a","https://git.kernel.org/stable/c/6864c789b570e57f932847fa83f6b56917182d73","https://git.kernel.org/stable/c/7a94138caeb27f3c49c1dbd93bf422098925bb28","https://git.kernel.org/stable/c/99fc088d6cc6890ae35fa2f29c50ebe027844c20"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:46:40.600842820+00:00"},"epss":{"cve":"CVE-2026-64462","score":0.00184,"percentile":0.08052,"date":"2026-10-31"},"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).
