Use After Free #cybersecurity #reverseengineering

A use-after-free vulnerability occurs when a program continues to use memory that has been freed, leading to potential security exploits. In this case study, the Cache Manager binary demonstrates how failing to nullify a pointer after calling free() allows attackers to reuse the freed memory address, enabling arbitrary code execution through heap corruption. The fix requires adding a single line to set the pointer to NULL after freeing, preventing the dangling pointer from being exploited.
