Vulnerability Title
intel_th: msu: Fix vmalloced buffers
Source: NVD (National Vulnerability Database)
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: intel_th: msu: Fix vmalloced buffers After commit f5ff79fddf0e ("dma-mapping: remove CONFIG_DMA_REMAP") there's a chance of DMA buffer getting allocated via vmalloc(), which messes up the mmapping code: > RIP: msc_mmap_fault [intel_th_msu] > Call Trace: > <TASK> > __do_fault > do_fault ... Fix this by accounting for vmalloc possibility.
