    Apple fixed tons of bugs today. Like everyone else, I got 3 CVE credits today. Here's the 2nd one - CVE-2026-64696 is my second one - macOS Kernel Heap Over-Read and Heap Corruption via TOCTOU in in SMB. This vulnerability allows the attacker to achieve two distinct primitives - a Kernel heap information leak (READ), and a Kernel heap corruption.
