AI-suggested
A fix is available that injects synchronization instructions around the lld/scd loops to enforce ordering guarantees on affected CPUs. Users should update to patched Linux kernel versions that include this fix. Since this is a kernel-level issue, applying the official kernel updates from the vendor or distribution is the recommended remediation.
Description
A vulnerability in the Linux kernel affects MIPS I6500 CPU cores due to improper ordering guarantees in load-linked/store-conditional (lld/scd) instructions. This can cause kernel paging faults and system crashes when the CPU reorders these instructions, violating assumptions about atomic operations. The issue has been resolved by injecting synchronization instructions around the lld/scd loops using existing infrastructure. The vulnerability impacts specific Linux kernel versions used in various Ubuntu LTS releases.
