      "value": "In the Linux kernel, the following vulnerability has been resolved:\n\ngpio: exar: initialize the ID before registering its cleanup\n\ndevm_add_action_or_reset() invokes the cleanup action immediately when\nregistering the action fails.  gpio_exar_probe() currently stores the\nallocated ID in exar_gpio only after registering the action, so that\nfailure makes exar_devm_ida_free() release ID 0.  If the allocated ID is\nnonzero, this leaks that ID and can free ID 0 belonging to another device.\n\nStore the ID before registering the cleanup action so both the immediate\nfailure path and normal device teardown release the correct allocation."
