Description OSIDB Bzimport 2026-05-01 15:07:12 UTC 
In the Linux kernel, the following vulnerability has been resolved:

nvmem: zynqmp_nvmem: Fix buffer size in DMA and memcpy

Buffer size used in dma allocation and memcpy is wrong.
It can lead to undersized DMA buffer access and possible
memory corruption. use correct buffer size in dma_alloc_coherent
and memcpy.
