CVE-2025-43300Apple Image I/O — malicious image corrupts memory

The image handling framework across iOS, iPadOS and macOS writes outside its buffer on a crafted image file, so simply processing one corrupts memory. Apple fixed it across seven release branches at once.

YOUR NEXT MOVE

Update to iOS and iPadOS 18.6.2, 17.7.10, 16.7.12 or 15.8.5, and macOS 15.6.1, 14.7.8 or 13.7.8 now; images arrive without any click.
