{"id":"CVE-2026-64230","summary":"regulator: tps65219: fix irq_data.rdev not being assigned","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nregulator: tps65219: fix irq_data.rdev not being assigned\n\nCommit 64a6b577490c (\"regulator: tps65219: Remove debugging helper\nfunction\") removed the tps65219_get_rdev_by_name() helper along with\nthe irq_data.rdev assignment that depended on it. This left\nirq_data.rdev uninitialized for all IRQs, causing undefined behavior\nwhen regulator_notifier_call_chain() is called from the IRQ handler:\n\n  Internal error: Oops: 0000000096000004\n  pc : regulator_notifier_call_chain\n  lr : tps65219_regulator_irq_handler\n  Call trace:\n   regulator_notifier_call_chain\n   tps65219_regulator_irq_handler\n   handle_nested_irq\n   regmap_irq_thread\n   irq_thread_fn\n   irq_thread\n   kthread\n   ret_from_fork\n\nInstead of restoring a dedicated lookup array, restructure the probe\nfunction to combine regulator registration with IRQ registration in\nthe same loop. This way the rdev returned by devm_regulator_register()\nis naturally available for assigning to irq_data.rdev without any\nauxiliary data structure.\n\nNon-regulator IRQs (SENSOR, TIMEOUT) that don't correspond to any\nregistered regulator are registered with rdev=NULL, and the IRQ handler\nis protected with a NULL check to avoid crashing.","modified":"2026-07-27T04:03:20.571886203Z","published":"2026-07-24T15:23:12.616Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64230.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/6827647fd2dcf4e7f355478a42e82f51e0b5344c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b986f88b22a5374191c195c073350bbeb1bb6518"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f9b2d3b703d13df50c630997dfdc25648e96db0d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64230.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64230"},{"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":"64a6b577490c1c71f1a3bbdb3844717815214621"},{"fixed":"6827647fd2dcf4e7f355478a42e82f51e0b5344c"},{"fixed":"b986f88b22a5374191c195c073350bbeb1bb6518"},{"fixed":"f9b2d3b703d13df50c630997dfdc25648e96db0d"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64230.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.14.0"},{"fixed":"6.18.34"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.11"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64230.json"}}],"schema_version":"1.7.5"}
