This patch addresses a use-after-free (UAF) vulnerability in the sys_mount. The issue occurred due to improper handling of memory deallocation, which could lead to crashes or undefined behavior on user request of mounting. Changes made: - Moved the `rt_free(copy_source)` function call to occur after the necessary operations are completed, preventing premature deallocation of memory.
