This bug is triggered by running a dynamic analysis on the kernel, with the help of sanitizer to observe this bug. This memory overlapping copy can cause data corruption when scr_memcpyw is optimized to memcpy because memcpy does not ensure its behavior if the destination buffer overlaps with the source buffer.
