Security vulnerabilities and automated fixes for null pointer dereference issues
1 post found
A high-severity NULL pointer dereference vulnerability was discovered and fixed in embedded eMMC storage handling code, where unchecked `malloc` and `calloc` return values could allow an attacker with a crafted eMMC image to crash the host process. The fix adds proper NULL checks after every memory allocation, preventing exploitation through maliciously oversized partition size fields. This type of vulnerability is surprisingly common in systems-level C code and serves as a reminder that defensi
