A critical integer overflow vulnerability was discovered and patched in `rtg/mntgfx-gcc.c`, where an unvalidated bit-shift operation used to compute a graphics pattern blit copy size could trigger undefined behavior, silent data corruption, or a devastating out-of-bounds memory write. This post breaks down exactly how a single missing bounds check can turn a routine graphics operation into a serious security and stability threat, and what developers can do to prevent similar issues in their own
