CVE-2026-98228 is a vulnerability in the Linux kernel affecting MIPS architecture, specifically on I6500 CPU cores. The issue arises because the load-linked (lld) and store-conditional (scd) instructions do not provide ordering guarantees, which can lead to kernel paging faults and system instability. The vulnerability is related to weak memory ordering assumptions in the arch_cmpxchg() implementation. A fix involves injecting synchronization instructions around these loops to ensure proper ordering and prevent faults.
