memory allocator bug

About this tag
The memory allocator bug tag on WindowsForum.com covers discussions about small allocation mismatches in kernel-level code, such as the CVE-2026-46068 vulnerability in the Linux kernel's IBM Power NX 842 crypto driver. This flaw involved using free_page() instead of free_pages() for order-2 bounce-buffer allocations, a subtle mismatch that can lead to memory corruption. While the practical risk is narrow, the tag highlights how such bugs are increasingly tracked as vulnerabilities, serving as a reminder for administrators managing mixed Windows-and-Linux environments to understand allocator correctness in kernel code.
