Description
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.
