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.","state":0,"publishedAt":"2026-09-17T16:06:26.567+00:00","modifiedAt":"2026-10-19T08:58:21.572+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/irqchip/irq-ast2700-intc0.c\",\n                        \"drivers/irqchip/irq-ast2700-intc1.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"07825e41519abb8ac13d6d1c553af47f57775f6b\",\n                            \"lessThan\": \"f2f0da11648616e47419dca93610f6c0d70ec00b\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"07825e41519abb8ac13d6d1c553af47f57775f6b\",\n                            \"lessThan\": \"b76eee9c2157223aa4aac42ceebb563288e078aa\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/irqchip/irq-ast2700-intc0.c\",\n                        \"drivers/irqchip/irq-ast2700-intc1.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"7.2\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"7.2\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.6\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/f2f0da11648616e47419dca93610f6c0d70ec00b","https://git.kernel.org/stable/c/b76eee9c2157223aa4aac42ceebb563288e078aa"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-90123","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-90123","identifiers":["CVE-2026-90123"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
