CVE-2025-39869

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

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

Fix a critical memory allocation bug in edma_setup_from_hw() where

queue_priority_map was allocated with insufficient memory. The code

declared queue_priority_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:

queue_priority_map[i][0] = i;

queue_priority_map[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(*queue_priority_map) which

automatically gets the correct size for the 2D array structure.
