W^X
A memory protection policy requiring that no memory page be simultaneously writable and executable, used to prevent memory injection and shellcode execution attacks.
Timeline (last 90 days)
OpenBSD enables the W^X (write XOR execute) policy by default, requiring that the same memory page cannot be both writable and executable.
Porting Wine to OpenBSD requires resolving conflicts between OpenBSD-specific security mechanisms (such as W^X and pledge/unveil) and the runtime requirements of Wine.
W^X (Write XOR Execute) is a memory protection policy enforced by OpenBSD on most architectures since version 5.8, requiring that no memory page be both writable and executable.
