摘要: A method for preventing time of check to time of use exploits includes receiving a system call from a user space at a system call intercept and copying user space parameters from the user space to a kernel space responsive to the system call. The method also includes copying the user space parameters from the kernel space to a secure location in the user space, receiving the user space parameters from the secure location at the system call intercept, and executing the system call based on the received user space parameters. A computer readable medium including computer readable code and a system for executing the method steps are also disclosed.
