fkie_cve-2026-98228

In the Linux kernel, the following vulnerability has been resolved:

mips: select CONFIG_WEAK_REORDERING_BEYOND_LLSC from CONFIG_EYEQ

On I6500 CPU cores, lld and scd give no ordering guarantees (same as all other instructions). To respect the assumption that arch_cmpxchg() is fully ordered, we must inject sync instructions above and below our lld/scd loops using the already in place WEAK_REORDERING_BEYOND_LLSC infrastructure.

Otherwise, bad things can happen:
