ibm power nx 842

The tag 'ibm power nx 842' covers discussions about the IBM Power NX 842 crypto compression engine, particularly in the context of Linux kernel vulnerabilities. A recent thread highlights CVE-2026-46068, a small allocator mismatch where free_page() was incorrectly used instead of free_pages() for order-2 bounce-buffer allocations during cleanup. This vulnerability is specific to the NX 842 crypto compression context and has a narrow practical risk. The discussion serves as a reminder that even minor memory management errors in kernel code can become tracked CVEs, relevant for administrators managing mixed Windows-and-Linux environments with IBM Power hardware.
