Last modified

CVE-2011-3982 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.33% chance of exploitation in the next 30 days.
