Both\naspeed_intc1_irq_domain_activate() and aspeed_intc0_resolve_route() test a\ncompatible string with fwnode_device_is_compatible().\n\nfwnode_device_is_compatible() invokes fwnode_property_match_string(), which\nallocates with GFP_KERNEL. That's obviously not possible with interrupts\ndisabled and a raw spinlock held.\n\nBoth call sites are only ever handed OF nodes, so use\nof_device_is_compatible() instead: it walks the property in place and does\nnot allocate.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/b76eee9c2157223aa4aac42ceebb563288e078aa","https://git.kernel.org/stable/c/f2f0da11648616e47419dca93610f6c0d70ec00b"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-90123","score":0.00198,"percentile":0.09408,"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).
