In the Linux kernel, the following vulnerability has been resolved:
intel_th: 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 do_fault ...
Fix this by accounting for vmalloc possibility.
