{"id":"CVE-2026-53226","summary":"gpio: rockchip: fix generic IRQ chip leak on remove","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ngpio: rockchip: fix generic IRQ chip leak on remove\n\nThe driver allocates domain generic chips using\nirq_alloc_domain_generic_chips() during probe. However, on driver\nremove/teardown, the generic chips are not automatically freed when the\nIRQ domain is removed because the domain flags do not include\nIRQ_DOMAIN_FLAG_DESTROY_GC.\n\nThis causes both the domain generic chips structure and the associated\ngeneric chips to be leaked. Additionally, the generic chips remain on\nthe global gc_list and may later be visited by generic IRQ chip suspend,\nresume, or shutdown callbacks after the GPIO bank has been removed,\npotentially resulting in a use-after-free and kernel crash.\n\nFix the resource leak by explicitly calling\nirq_domain_remove_generic_chips() before removing the IRQ domain in\nrockchip_gpio_remove().","modified":"2026-07-08T08:13:43.896646929Z","published":"2026-06-25T08:39:26.567Z","related":["CGA-m279-pqxv-4433"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53226.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1c1e0fc88d6ef65bf15d517853251f75ab9d18c3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1f34ea5f6114011092d9a5c8b901ad6741144a1d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bace7b99bfa555fe833aee8827b8004c43666d02"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53226.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53226"},{"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":"936ee2675eee1faca0dcdfa79165c7990422e0fc"},{"fixed":"bace7b99bfa555fe833aee8827b8004c43666d02"},{"fixed":"1f34ea5f6114011092d9a5c8b901ad6741144a1d"},{"fixed":"1c1e0fc88d6ef65bf15d517853251f75ab9d18c3"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53226.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.15.0"},{"fixed":"6.18.36"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.13"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53226.json"}}],"schema_version":"1.7.5"}
