Executive Summary

This vulnerability involves the Linux kernel on ARM Tegra devices where the kernel crashes due to the use of the normal memcpy function when writing to IRAM. The Kernel Address Sanitizer (Kasan) attempts to check memory boundaries during this operation, leading to a crash. The issue was resolved by using an I/O memcpy function instead of the normal memcpy for writing to IRAM.

Impact Analysis

This vulnerability can cause the Linux kernel to crash on affected ARM Tegra devices, potentially leading to system instability or denial of service.
