"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nclk: qcom: gdsc: tear down per-domain genpds in gdsc_unregister()\n\ngdsc_unregister() removes the OF provider entry and tears down the\nparent/subdomain wiring, but never calls pm_genpd_remove() on the\nindividual generic_pm_domain structures registered by gdsc_init():\n\n\tvoid gdsc_unregister(struct gdsc_desc *desc)\n\t{\n\t\tstruct device *dev = desc->dev;\n\t\tsize_t num = desc->num;\n\n\t\tgdsc_pm_subdomain_remove(desc, num);\n\t\tof_genpd_del_provider(dev->of_node);\n\t}\n\nThat leaves dangling entries on the global gpd_list. After a provider\nunbind/rebind cycle (deferred-probe replay during early boot, real\nmodule unload of a clk driver that owns GDSCs, or an OF-overlay tear-\ndown) the next gdsc_init() will end up trying to re-register a name\nthat is still in the list and pm_genpd_init() returns -EEXIST.\n\nWhile we are here, flip the order so the consumer-facing OF provider\nentry is the first thing removed -- otherwise a fresh\nof_genpd_get_from_provider() call racing with the teardown could\nattach to a domain that is mid-removal.\n\nIterate the scs[] array and pm_genpd_remove() each registered domain\nafter the subdomain links are torn down. The regulators stay devm-\nmanaged (devm_regulator_get_optional() in gdsc_register()), so the\nrelease happens automatically when the underlying device is unbound;\njust the genpd accounting needs to be undone explicitly."
