Part 1/4:
The Battle Against Memory Corruption Vulnerabilities
In the ever-evolving world of cybersecurity, memory corruption vulnerabilities remain a persistent threat. As we enter the year 2024, this issue continues to be the number one cause of hacks, posing a significant challenge to developers and security experts alike.
However, the Linux kernel is introducing a new feature called mseal - a new system call that aims to address this problem. This innovative approach has sparked a lively debate within the Linux community, particularly from the renowned Linus Torvalds.
Understanding Memory Corruption Vulnerabilities
Memory corruption vulnerabilities arise when a program fails to properly manage the memory it uses. This can happen when a buffer is overflowed, or when a program uses memory after it has been freed (use-after-free). These vulnerabilities allow hackers to gain code execution on a victim's computer, posing a significant security risk.
