CVE-2026-31743

About vulnerability

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 flaw was found in the Linux kernel, specifically within the nvmem and zynqmp_nvmem modules. An incorrect buffer size used during Direct Memory Access (DMA) allocation and memcpy operations can lead to undersized DMA buffer access. This vulnerability could allow a local attacker to cause memory corruption, potentially leading to system instability or denial of service.

Live-patch status from KernelCare for each operating system.
