  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nspi: davinci: switch to managed controller allocation\n\nThe controller is allocated with the non-managed spi_alloc_host() while\nthe interrupt is registered with devm_request_threaded_irq().  During\nremoval, spi_bitbang_stop() only unregisters the controller; the\nsubsequent spi_controller_put() then frees the controller together with\nits embedded davinci_spi devdata, which is the IRQ handler's dev_id.\nThe devm_request_threaded_irq() release action (free_irq()), which\ndrains the handler, does not run until after .remove() returns.  A late\nor latched interrupt can therefore reach davinci_spi_irq() and\ndereference already-freed memory.\n\nSwitch to devm_spi_alloc_host() so that the devres LIFO order releases\nthe controller only after free_irq() has drained the handler, and drop\nthe now-redundant spi_controller_put() from .remove().  The probe error\npath is simplified to direct returns.\n\nThe clock is acquired with devm_clk_get_enabled(), which is registered\nafter the IRQ and thus released before it by the devres LIFO order.\nDrain the interrupt explicitly with devm_free_irq() before disabling the\ncontroller so that a late interrupt cannot access the registers of a\nclock-gated controller.\n\nThis issue was found by an in-house static analysis tool.",
