| PXI [[RPC_Command_Structure|Command]] input/output buffer permissions
| Originally the ARM11-kernel didn't check permissions for PXI input/output buffers for commands. Starting with [[6.0.0-11|6.0.0]] PXI input/output buffers must have RW permissions, otherwise kernelpanic is triggered.

* Syscalls that allocate a variable-length array on stack, only checked bit31 before multiplying by 4/16 (when calculating how much memory to allocate). If a large integer was passed as input to one of these syscalls, an integer overflow would occur, and too little memory would have been allocated on stack resulting in a buffer overrun.

This might allow for ARM11 kernel code-execution.
