Details

In the Linux kernel, the following vulnerability has been resolved: lib/testhmm.c: handle srcpfns and dstpfns allocation failure The kcalloc() in dmirrordeviceevictchunk() will return null if the physical memory has run out. As a result, if srcpfns or dstpfns is dereferenced, the null pointer dereference bug will happen. Moreover, the device is going away. If the kcalloc() fails, the pages mapping a chunk could not be evicted. So add a _GFPNOFAIL flag in kcalloc(). Finally, as there is no need to have physically contiguous memory, Switch kcalloc() to kvcalloc() in order to avoid failing allocations.
