In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
dibs: initialise dibs->lock in dibs_dev_alloc()<\/p>\n
dibs->lock 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->lock unconditionally on entry, before it
\ninspects anything else.<\/p>\n
Initialise 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.<\/p>\n","protected":false},"excerpt":{"rendered":"
