Nodes in a distributed node system are configured to support memory corruption detection when memory is shared between the nodes. Nodes in the distributed node system share data in units of memory referred to herein as “shared cache lines.” A node associates a version value with data in a shared cache line. The version value and data may be stored in a shared cache line in the node's main memory. When the node performs a memory operation, it can use the version value to determine whether memory corruption has occurred. For example, a pointer may be associated with a version value. When the pointer is used to access memory, the version value of the pointer may indicate the expected version value at the memory location. If the version values do not match, then memory corruption has occurred.
