Summary
dmaengine: ti: edma: Fix memory allocation size for queue_priority_map
Details

In the Linux kernel, the following vulnerability has been resolved:

dmaengine: ti: edma: Fix memory allocation size for queueprioritymap

Fix a critical memory allocation bug in edmasetupfromhw() where queueprioritymap was allocated with insufficient memory. The code declared queuepriority_map as s8 (*)[2] (pointer to array of 2 s8), but allocated memory using sizeof(s8) instead of the correct size.

This caused out-of-bounds memory writes when accessing: queueprioritymap[i][0] = i; queueprioritymap[i][1] = i;

The bug manifested as kernel crashes with "Oops - undefined instruction" on ARM platforms (BeagleBoard-X15) during EDMA driver probe, as the memory corruption triggered kernel hardening features on Clang.

Change the allocation to use sizeof(*queueprioritymap) which automatically gets the correct size for the 2D array structure.
