Description (CNA)
The Fibre Channel driver for QLogic adapters in IBM AIX 6.1 and 7.1 does not properly handle DMA resource limitations, which allows local users to cause a denial of service (system hang) via vectors that generate a large amount of DMA I/O, related to a deadlock in timer processing across CPUs.
