A method, a computing system and a computer program product are provided. A first process of multiple processes sets access rights regarding a shared memory buffer from a shared memory to read/write, the shared memory buffer having been allocated and provided to the first process by a second process of the multiple processes. The first process sets access rights regarding a supplemental memory area of the shared memory buffer to no access, the supplemental memory area being before a usable buffer portion of the shared memory buffer, after the usable buffer portion of the shared memory buffer, or both before and after the usable buffer portion of the shared memory buffer. The first process stops executing when the first process attempts to access any portion of the supplemental memory area.
