CVE-2026-31743 Details
Description
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.
A vulnerability exists in the Linux kernel's handling of buffer sizes within the Zynqmp NVMEM driver. The issue arises from incorrect buffer size allocations for Direct Memory Access (DMA) operations and memory copying functions. This miscalculation can lead to inadequate DMA buffer access, potentially causing memory corruption. The vulnerability affects the stable version of the Linux kernel.
Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability.
