CVE-2022-49440

CVE-2022-49440 affects the Linux kernel (PowerPC RTAS path). The root cause is MSR[RI] not being preserved when entering RTAS, while RTAS runs in real mode and may trigger a panic/ watchdog lockup if MSR[RI] is unset. The fix updates how MSR is computed before calling RTAS, ensuring a hardcoded v...
