AlmaLinux OS 9 must implement nonexecutable data to protect its memory from unauthorized code execution.
Description
Discussion Text
ExecShield uses the segmentation feature on all x86 systems to prevent execution in memory higher than a certain address. It writes an address as a limit in the code segment descriptor, to control where code can be executed, on a per-process basis.
When the kernel places the memory regions of a process, such as the stack and heap, higher than this address, the hardware prevents execution in that address range.
