Memory Access Vulnerability in Linux Kernel on 6G DSI Platforms

CVE-2026-64231

What is CVE-2026-64231?

A vulnerability in the Linux kernel affects DSI 6G platforms, where an improperly managed I/O address space can lead to unauthorized memory access. The issue arises from the incorrect adjustment of memory dumping size, failing to account for the io_offset. Consequently, this oversight allows potential exposure to unmapped regions of memory. To mitigate this risk, the control size needs to be reduced by the io_offset value, preventing access beyond the mapped area. For detailed technical insights, refer to the patch documentation.
