In 2024, memory corruption remains the leading cause of hacks. A new Linux kernel feature called mseal aims to mitigate this by preventing hackers from exploiting vulnerabilities. mseal, developed by Jeff Zoo, seals a memory page, making it impossible to change its permissions or expand it, thus hindering common hacking techniques like buffer overflows. This feature, however, comes with some limitations, particularly regarding its application to the heap and stack memory regions.
