CVE-2024-42230

In CVE-2024-42230, the Linux kernel on pseries PowerPC is affected by a scv instruction crash when kexec is used. The root cause is that kexec on pseries disables AIL (reloc_on_exc), required for scv instruction support, before all CPUs have been shut down, allowing scv instructions to execute af...
