The vulnerability is that stat() follows symbolic links, but the program relies on the filename string argv[1] remaining constant. race condition hackviser

If you want to get good at binary exploitation, don't ignore the low-hanging fruit. Sometimes, the kernel’s scheduler is your best exploit primitive. # Link points to target (Exploit use) ln -sf /root/flag

A race condition is a type of concurrency bug that arises when multiple processes or threads try to access a shared resource, such as a file, socket, or variable, at the same time. This can lead to unpredictable behavior, including crashes, data corruption, or unexpected results. In a race condition, the outcome depends on the relative timing of the processes or threads, making it challenging to predict and reproduce. A race condition is a type of concurrency
