CVE-2025-38401

HIGH

Linux Kernel 4.2-6.15.6 - Memory Corruption via DMA Map Failure in mtk-sd

Title source: llm
STIX 2.1

Description

In the Linux kernel, the following vulnerability has been resolved: mtk-sd: Prevent memory corruption from DMA map failure If msdc_prepare_data() fails to map the DMA region, the request is not prepared for data receiving, but msdc_start_data() proceeds the DMA with previous setting. Since this will lead a memory corruption, we have to stop the request operation soon after the msdc_prepare_data() fails to prepare it.
