{"id":"CVE-2026-90123","summary":"irqchip/ast2700-intc: Avoid allocating in the irq_domain activate() callback","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nirqchip/ast2700-intc: Avoid allocating in the irq_domain activate() callback\n\nThe interrupt core calls the irq_domain_activate() callback from\n__setup_irq() with desc-\u003elock held and interrupts disabled. 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.","modified":"2026-09-19T03:47:28.615834360Z","published":"2026-09-17T16:06:26.567Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90123.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/b76eee9c2157223aa4aac42ceebb563288e078aa"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f2f0da11648616e47419dca93610f6c0d70ec00b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90123.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90123"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"07825e41519abb8ac13d6d1c553af47f57775f6b"},{"fixed":"f2f0da11648616e47419dca93610f6c0d70ec00b"},{"fixed":"b76eee9c2157223aa4aac42ceebb563288e078aa"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90123.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.2.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90123.json"}}],"schema_version":"1.9.0"}
