Memory Boundary Vulnerability in the Linux Kernel for ARM Tegra Products

CVE-2025-39794

What is CVE-2025-39794?

A critical issue has been identified in the Linux kernel related to the ARM Tegra architecture. The vulnerability arises when the kernel attempts to use the standard memcpy function to write to IRAM, leading to potential crashes when Kasan, the kernel address sanitizer, checks for boundaries. This flaw poses a risk of instability and unreliable operation in systems utilizing the affected components, particularly when proper memory boundary checks are bypassed during operations.
