In the Linux kernel, the following vulnerability has been resolved: intelth: msu: Fix vmalloced buffers After commit f5ff79fddf0e ("dma-mapping: remove CONFIGDMAREMAP") there's a chance of DMA buffer getting allocated via vmalloc(), which messes up the mmapping code: > RIP: mscmmapfault [intelthmsu] > Call Trace: > <TASK> > _dofault > dofault ... Fix this by accounting for vmalloc possibility.
