  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndibs: initialise dibs-\u003elock in dibs_dev_alloc()\n\ndibs-\u003elock is initialised by dibs_dev_add(), but a dibs device can\nalready take interrupts before that call: ism_probe() runs\nism_dev_init(), and hence request_irq(), before it calls\ndibs_dev_add(). No client can have registered a dmb at that point, so\nno dmb interrupt can occur, but a GID event interrupt can, and\nism_handle_irq() takes dibs-\u003elock unconditionally on entry, before it\ninspects anything else.\n\nInitialise the lock in dibs_dev_alloc() instead, so that it is valid as\nsoon as a driver can publish the device to its interrupt handler.",
