CVE-2022-49440 powerpc/rtas: Keep MSR[RI] set when calling RTAS

In the Linux kernel, the following vulnerability has been resolved: powerpc/rtas: Keep MSRRI set when calling RTAS RTAS runs in real mode MSRDR and MSRIR unset and in 32-bit big endian mode MSRSF,LE unset. The change in MSR is done in enterrtas in a relatively complex way, since the MSR value cou...

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...
