Title
RDMA/efa: Keep admin queues alive while IRQ is registered
Summary
In the Linux kernel, the following vulnerability has been resolved: RDMA/efa: Keep admin queues alive while IRQ is registered The management IRQ handler accesses both the admin completion queue and the async event queue. The driver registered the IRQ before constructing these queues and destroyed them before freeing the IRQ, so the handler's lifetime was not contained by the resources it accesses. Initialize the queues with interrupts masked, request the IRQ, and then switch to interrupt mode. On removal, reset the device and free the IRQ before destroying the queues. Also reset the device before destroying the queues if IRQ registration fails, because the device already has their DMA addresses.

The driver registered the IRQ before constructing these\nqueues and destroyed them before freeing the IRQ, so the handler\u0027s lifetime\nwas not contained by the resources it accesses.\n\nInitialize the queues with interrupts masked, request the IRQ, and then\nswitch to interrupt mode. On removal, reset the device and free the IRQ\nbefore destroying the queues. Also reset the device before destroying the\nqueues if IRQ registration fails, because the device already has their DMA\naddresses."
